Certainly if the ACIA Tx Interrupt is slow to be serviced, then the ACIA master reset write would be delayed.

i.e. there clearly the potential for a race condition between the interrupt handler and the first of the two extra bytes.

This might allow part of the first byte of extra data to "leak out".

Can you say anything about the range of values you see when this extra byte is present. Are the higher numbered bits typically '1'?

The interrupt might be slow to be serviced if another interrupt is pending. But think is unlikely to affect all blocks in the same program equally. It would be pretty random.

I wonder if there is a way the presence of certain paged ROMs might delay the interrupt processing? That might cause the behaviour to be consistent on a particular machine.

Also, it might be different on a Master.

I should be making dinner, but apparently this is more important.

So I did indeed manage to find one of the candidate titles within the vanekp WAV tape archive -- Caveman Adventure.

I grabbed "CavemanAdventure(ProgramPower).wav" from this WAV archive, and ran it through Quadbike. By default, Quadbike just produces a CSW output file, but the --inspect-dir debugging option tells it to dump useful intermediate data into various WAV files in a specified directory -- essentially, it allows you to "see what Quadbike is thinking".

Here is the very end of block 0 of the first file on the tape, according to Quadbike.

The top trace here is the 1-bit (2400 Hz) signal power, according to the Goertzel transform employed by Quadbike to identify bits. Below that is a sync stream derived from it, which shows where each pair of half-bits is sampled from the power. The bottom trace is the resulting decoded bitstream, which I have annotated with the bit values. Remember that bytes are sent LSB first, so the bits in each byte are read right to left, resulting in a sequence of DD 7B 7B as the final three bytes in the block.

Similarly, here's block 1:

So we would expect sequences of DD 7B 7B, and 80 31 31, for the final three bytes of the first two blocks on the tape. It certainly looks like there is a single duplicated CRC byte involved here, but what does the hacked Cornfield say about the UEF file from Stairway -- "CavemanAdventure_B.uef"? Does it agree?

Code: Select all

  stardot: blk #1: 1 garbage bytes; first matches CRC MSB (7b :: 7bdd)
  0x0153  4e dd 7b 7b
  stardot: blk #2: 1 garbage bytes; first matches CRC MSB (31 :: 3180)
  0x027d  69 80 31 31

You bet it does.

Good question. Not really. There seems to be a fairly even distribution for the most part, and all possible byte values seem to appear at least once. However, &FB is overwhelmingly the most common repeated CRC byte (62 occurrences, versus just 34 for its nearest rival, &D1). If I had to guess, I'd suggest that this is just because certain CRCs are more common than others, based on certain code (and therefore blocks) being shared between multiple tapes?

For completeness, here's a list: the frequency first, followed by the byte value it applies to, in case anyone wants to plot a graph or anything:

Code: Select all

Also, it might be different on a Master.

Or an Electron? I wonder if this is it. I don't know what the date distribution of the titles in that sub-corpus looks like. One of the tapes that exhibits this phenomenon is Snapper, which was obviously an early game -- the UEF claims to be version 1 -- but I'm sceptical of that claim, since the weird Acornsoft "version files" don't appear in the UEF.

Might it go the other way? I wonder if any of these UEFs were saved on OS 0.1? Or 0.1 with the Richard Russell CFS in-memory patch for the filing system bug? Or even OS 1.0 (which I think did briefly exist)?

Hmm ... don't we have the Acorn source code for MOS somewhere?

The problem is not with any build UEF files (so not with CSW or makeuef) but the extra CRC bytes appear ONLY when you save something in BeemEm to a UEF image that it adds extra CRC bytes.
If I raw dump a tape file on the BBC there are no extra bytes if I raw dump a uef made in BeemEm then it has the extra CRC bytes in the file.

No. It is not that simple.

I've already found real tape dumps that contain 1 extra byte after the CRC -- there is at least 1 of them in your own tape archive:

Thanks ... yeah, I was just looking at this. I was hoping there might be a comment that provided some insight, but there's nothing compelling.

I still want to know why a minority of real-world tapes are leaking a single duplicate CRC byte.

I would try MOS 0.1 if I had a way of getting it into ROM, but I don't.

I'm still not sure about this either.

All of the critical stuff is occurring during the stop bit (at the end of the second CRC byte), so it's useful to consider the timeline of this bit:

Code: Select all

  0us: beginning of stop bit
416us: ACIA asserts IRQ (Tx Data Empty)
478us: IRQ Handler writes to TxD and ACIA releases IRQ
516us: resetACIA code writes to ACIA Control, setting a Master Reset
832us: end of stop bit

From the distribution of the extra byte values, there isn't much evidence of the ACIA stopping mid-way through the byte. So it's likely that once the next start bit happens, the ACIA is committed to sending the byte.

So for the extra byte to be present, somehow the resetACIA call must be delayed by > 316us.

There is very often another interrupt correlated with the stop bit, and I haven't yet worked out what it is. But it never seems to delay things enough that I see an extra byte being transmitted. I did over a hundred tests in a loop.

So it appears this is not the case...

I did an experiment where I revectored IRQV1 to a delay loop, allowing me to introduce different amounts of delay. Once the delay exceeds ~400us you start to see the extra byte after the CRC, but it's clear the Master Reset takes effect immediately.

The data on the distribution of the extra bytes does not suggest the are being chopped in this way. So something else must be going on.

Looking at a disassembly of OS 0.10, the code after the CRC is different:

Code: Select all

    JSR .saveChecksumToTape                             ; save checksum to TAPE

.saveFinalTwoBytes
    JSR .saveByteAToTapeInternal                        ;
    INC .fsGotACharacterToReadOrWriteFlag               ;
    JSR .saveByteAToTapeInternal                        ;
    JSR .resetACIA                                      ;

and

Code: Select all

; ***************************************************************************************
.saveByteAToTapeInternal
    LDA #12                                             ;
    STA .verticalSyncCounter                            ; set to 12 vsyncs
-
    BIT .fsGotACharacterToReadOrWriteFlag               ;
    BMI +                                               ; if (byte written) then branch
    BIT .verticalSyncCounter                            ; check vertical sync counter
    BPL -                                               ; if (not timeout) then branch (loop back)
    JSR .checkForEscapeDuringCassetteOperation          ;
    BMI .saveByteAToTapeInternal                        ;

+
    ; byte is now read / written
    PHP                                                 ; store flags
    LDA #0                                              ; A=0
    STA .fsGotACharacterToReadOrWriteFlag               ; clear flag, we no longer have a byte
    PLP                                                 ; recall flags
    RTS

So I think the behavoiur of this is well worth someone investigating.

Dave,

Looking at the Acorn source you linked above, the routine that Toby calls 'saveByteAToTapeInternal' is called IWAIT and does not necessarily cause a byte to be written to tape. It is doing nothing with any of the ACIA regisrters. Instead it just waits for a flag byte, IFLAG, to go negative:

Code: Select all

IWAIT JSR ESCAPE
 BIT IFLAG
 BPL IWAIT

 LDAIM &00
 STA IFLAG ;Zero IFLAG
 LDA IBUF ;Restore A
 RTS  ;Note V preserved

IFLAG is obviously being set in the interrupt service routine. Here is the start of that:

Code: Select all

IRUPT

 DEC IFLAG
 LDA SROMSW ;Is SFS active ?
 BEQ NOTSPK ;Nope

At the point IFLAG is decremented and presumably becomes negative, the routine does not yet know what the cause of the interrupt is. Of course, the code looping on that flag won't see the change until the ISR returns so this could be undone again but that does not seem to be the case during the transmit code path.

As nothing new is loaded into IBUF, I think that means the two calls to IWAIT could cause up to two further copies of the last byte to be retransmitted, provided the source of the interrupt is the TX register becoming empty, but IWAIT will be satisfied by any interrupt from any source and in the case of non-tx-register-empty interrupts, nothing further will be transmitted.

I've changed BeebEm so that writing a master reset to the ACIA control register stops transmission, and this means BeebEm now writes only one duplicate CRC byte instead of two. I also fixed the UEF output so that the whole file is gzip compressed rather than compressing each UEF chunk separately, which fixes the incompatibility with other emulators.

A bit more on a possible OS 0.1 connection with that single repeated byte of CRC.

There are a total of 100 UEF files from Stairway that have a garbage byte that matches the CRC. I was able to find 76 of these on bbcmicro.co.uk, which enabled me to look up their year of release.

Out of 76 UEF files, well over half (45) have a release year of 1982. A further 28 are from 1983. Just three titles have release dates of 1984 or later (and bbcmicro.co.uk might have incorrect dates for one or more of these).

My money is now on the OS 0.1 CFS being responsible for the single-byte leak. hoglet's investigations seem to point quite strongly towards OS 1.2 not leaking anything, and this is backed up by the mass of UEFs that do not exhibit this phenomenon.

Can anyone test it on hardware? All we need is some programs saved using the cassette filing system with an OS 0.1 ROM installed, and then uploaded somewhere as WAV or FLAC. (The OS 0.1 block-zero cassette filing system bug in-memory patch by Richard Russell isn't compulsory for this, since it doesn't really matter if the start of a block gets corrupted.)

Space Hi-way (Amcom) (B) (Tape) [side-smalltabs] 1983 (on every block of the file)
SpaceHi-Way(Amcom) 1983 (on every block of the file)
YieArKung~FU(Imagine)(B)[SideLabel] 1985 (only has it on block YIE4 12 last block)
YieArKung~FU(Imagine)(B)[SideNoLabel] 1985 (has it only on 3 blocks)

some have it on every block some have it only on one or two blocks, I have also put the (c) date that I found in the program if there was one.
This is from a collection of 239 program that I have myself converted either from original tapes or from wav files that where given to my by a forum member.

I seem to remember that ctype is an old vs new compiler/language thing.
Are you using the supplied .vcxproj or another method?
If the vcxproj, did you upgrade it out leave it as it was?

I guess the one that comes with the downloaded beebem-windows-master from github.
would not know how to upgrade it, I am a newbie if it comes to compilers, normally stay well clear as I normally don't have much success.

I'm (slowly) implementing the 6850 TDR and TDSR for cassette output in BeebEm.

I have a question about the TDR empty interrupt. If a write to TDR happens when TDR and TDSR are both empty (and so the TDRE bit is set), how long does it take for the data to move from TDR to TDSR, and when should the TDR empty interrupt fire?

At the moment I've implemented that on a write, TDRE is cleared for a short time, after which TDR is copied to TDSR and TDRE is set and IRQ asserted. Is this the right approach, and how long should TDRE be cleared for in this case?

It looks like some of the Visual Studio files are missing, or the include paths aren't configured correctly. Did you install the 2019 version of Visual Studio Community? There's a 2022 version available, but I haven't tried it yet, so for now I'd recommend sticking with 2019.

Oh I though I did but just checked as see its ver 2022, thanks for the tip, will try to find the correct version as microsoft keeps trying to direct you to the latest one. sigh stupid microsoft it gives a link https://visualstudio.microsoft.com/vs/older-downloads/ wich just takes me back to downloading version 2022 GRRRRR

Thanks again chrisn for your help/tip.
Right after lots of loop hunting I finally found ver 2019, I am now able to compile it I successfully, I take it these warning error messages are normal as the program does run.

That's good news. The warnings are to be expected, I'm gradually working to remove them.

tricky · Post by **tricky** » Sat Aug 13, 2022 9:24 am

I can't remember if there is any profiling support in beebem, and can't find any reference to it, but I have added it to my version:

Code: Select all

6502core.cpp

int profile_counts[0x10000];

		profile_counts[ins.PC] += Cycles + CyclesTable[CurrentInstruction];



debug.cpp

extern int profile_counts[0x10000];
struct LabelCounts
{
	const Label * label;
	int cycle_count;
} label_counts[0x10001];


				case IDC_PROFILE:
					Profiling = (SendDlgItemMessage(hwndDebug, IDC_PROFILE, BM_GETCHECK, 0, 0) == BST_CHECKED);
					if (Profiling)
					{
						memset(profile_counts, 0, sizeof(profile_counts));
					}
					else if (FILE * file = log_fopen("profile.csv", "wt"))
					{
						memset(label_counts, 0, sizeof(label_counts));
						for (const Label & label : Labels)
						{
							label_counts[label.addr].label = &label;
						}
						std::vector<int> labels(1, 0x10000);
						for (int addr = 0; addr < 0x10000; ++addr)
						{
							if (label_counts[addr].label)
							{
								labels.resize(label_counts[addr].label->depth + 1, 0x10000);
								labels[label_counts[addr].label->depth] = addr;
							}
							for (int base : labels) label_counts[base].cycle_count += profile_counts[addr];
						}
						for (int addr = 0; addr < 0x10000; ++addr)
						{
							if (label_counts[addr].label)
							{
								const char * name = label_counts[addr].label->name;
								for (int i = 0; i < label_counts[addr].label->depth; ++i) name = strchr(name, '.') + 1;
								fprintf(file, "\"%s\",\"&%04X\",%i,%i,%s\"%s\"\n", label_counts[addr].label->name, addr, label_counts[addr].label->depth, label_counts[addr].cycle_count, ",,,,,,,,,,,,,,,,"+16-label_counts[addr].label->depth, name);
							}
						}
						fclose(file);
					}
					break;

It uses the labels exported from beebasm with the '.'s in to delimit sections of code.
.fun1
.fun1.sub1
.fun1.sub2
.fun2
Will show the total cycles from fun1 up to fun2 against fun1 and from fun1.sub1 up to fun1.sub2 against fun1.sub1 and then fun1.sub2 up to fun2 against fun1.sub1 so that fun1 will always be at least fun1.sub1 + fun1.sub2.
This is don't by summing the cycle counts for each address and then summing these for the ranges covered by the labels.
The results are written to profile.csv and look like:

Code: Select all

".fun1","&1000",1234,,"fun1"
".fun1.sub1","&1010",656,,,"sub1"
".fun1.sub2","&1020",512,,,"sub2"
...

I use a checkbox for controlling profiling, but it should work the same off the menu.
Enabling it clears the counts and then disabling it dumps the totals to "profile.csv".
While I have the cycle counts, I might add the instructions with counts too, similar to what I think Hoglet's code does for a HW capture.

I've just added a bit to the end of the output to dump the individual instruction costs:

Code: Select all

						fprintf(file, "\"Disassembly\"\n");
						for (int addr = 0; addr < 0x10000; ++addr)
						{
							if (profile_counts[addr])
							{
								if (label_counts[addr].label) fprintf(file, "\"%s\"\n", label_counts[addr].label->name);
								char opstr[256]; DebugDisassembleInstruction(addr, true, opstr);

								fprintf(file, ",%i,\"&%04X\",\"%c%c%c\",\"%c%c%c\",\"%c%c%c\",\"%s\"\n", profile_counts[addr], addr, opstr[5]==' '?' ':'&', opstr[5], opstr[6], opstr[8]==' '?' ':'&', opstr[8], opstr[9], opstr[11]==' '?' ':'&', opstr[11], opstr[12], opstr+14);
							}
						}

goes just before the fclose(file).

Produces this with a bit of manipulation of the existing DebugDisassembleInstruction() output.

Code: Select all

.wait_frame_mid						
	325	&04E5	&A5	&08	   	 LDA 08                   
.wait_frame_mid.wait						
	1340155	&04E7	&C5	&06	   	 CMP 06                   
	804031	&04E9	&F0	&FC	   	 BEQ 04E7                 
	390	&04EB	&60	   	   	 RTS                      
.wait_frame_mid_btm						
	390	&04EC	&20	&E5	&04	 JSR 04E5                 
.wait_frame_btm						
	325	&04EF	&A5	&08	   	 LDA 08                   
.wait_frame_btm.wait						
	578200	&04F1	&C5	&07	   	 CMP 07                   
	346855	&04F3	&F0	&FC	   	 BEQ 04F1                 
	585	&04F5	&E6	&08	   	 INC 08                   
	390	&04F7	&60	   	   	 RTS

The instructions will be what they were at thte end of the capture, so any self-modding may make the output make less sense.

PS Looks like some of the instruction timings are off at the point that I grabbed them so I might need to do some investigating.

PPS Fix is to move:
profile_counts[ins.PC] += Cycles + CyclesTable[CurrentInstruction];
to after:
Cycles += CyclesTable[CurrentInstruction] -
CyclesToMemRead[CurrentInstruction] - CyclesToMemWrite[CurrentInstruction];
and just use:
profile_counts[ins.PC] += Cycles;
which was what I had first and can't reproduce what I did to convince myself that I was wrong!

Hi,

I've just posted an issue on github about an issue I'm having when a sw ram back is paged in and a break point is set above &8000 on the code running in the bank... hopefully that was the right place to post the problem:

https://github.com/stardot/beebem-windows/issues/110

Cheers.

I also discovered the extra byte on the end of some cassette blocks. I would guess it was fixed along with the introduction of the dummy byte in the carrier tone. It would be useful to update BeebWiki about this and also the empty block flag of BBC blocks.

Either GitHub or here is fine, thank you for posting. I just PM''d you a link to a private build that hopefully fixes the problem you're having.

Hi Chris,

Apologies for the delay in responding to you, I've been away. Thanks for sending the new build through - much appreciated.

I'm still getting the crash unfortunately, the same thing happens when the breakpoint is hit with code between &8000 to CFFF.

I can send you though my code if thats of use to you.

Thanks.

That might be helpful to track this bug down. Thank you!

richmond62 · Post by **richmond62** » Sat Nov 19, 2022 9:53 am

I am assuming (on little or no evidence) that Richard Bannister's Horizon has not 'been back' to look at BeebEm's code since he
hived the thing off from MacBeebEm?

So, basically, any improvements he has are related to its performance on Macs rather than BBC Emulation?

Getting an answer out of him is not much easier than getting milk out of a stone.

So, would be grateful to a pointer towards any sort of Mac port (I have played around with a MacBeebEm 5 beta)
that is vaguely uptodate with BeebEm.

tricky · Post by **tricky** » Sat Nov 19, 2022 10:10 am

I can't help with beebem, but I think beebjit works on Mac.
b2 is also for Mac, why do I keep forgetting b2!
