acvirus.cpp - Access Virus series
|
||||
|
||||
Skeleton driver by R. Belmont
|
||||
|
||||
Hardware in brief:
|
||||
Virus A: SAB 80C535-N (12 MHz), DSP56303 @ 66 MHz
|
||||
Virus B: SAB 80C535-N (12 MHz), DSP56311 @ ??? MHz (illegible on PCB photo I've seen)
|
||||
Virus C: SAF 80C515-L24N (24 MHz), DSP56362 @ 120 MHz
|
||||
|
||||
Virus Rack is same h/w as B, Rack XL is the same h/w as C.
|
||||
Virus Classic is supposed to be the same h/w as B but not proven.
|
||||
|
||||
The various 80C5xx chips are i8051-based SoCs with additional I/O ports,
|
||||
256 bytes of internal RAM like the 8052, and an analog/digital converter.
|
||||
|
||||
The top 4 bits of port P5 select the bank at 0x8000. P5 is not implemented in
|
||||
any of the MCS-51 variants we support yet.
|
||||
|
||||
Hardware Notes:
|
||||
The DSP has three SRAM chips, probably 128 kbyte each
|
||||
for a total of 128 kwords, mapped to address 0x20000. All three DSP
|
||||
buses (P, X, Y) point to the same external memory. There's another 128
|
||||
kbyte of battery backed SRAM for the 8051.
|
||||
|
||||
The firmware image fits exactly in an AM29F040-120PC flash chip, and is
|
||||
bank switched into the 8051 program address space. The lower 0x8000
|
||||
bytes of the address space always points to the first 0x8000 bytes of
|
||||
flash (except during firmware upgrade, as I assume the programming
|
||||
routine has do run from RAM). The upper 0x8000 bytes of the address
|
||||
space can point to any 0x8000 sized bank in flash. A bank switch routine
|
||||
is at 0x64B8, and will switch to e.g. bank 2 (offset 0x10000) when A =
|
||||
0x20. The low nibble is usually zero, but not always, and I don't know
|
||||
how it's interpreted.
|
||||
|
||||
Banks 0-2 contain OS code and data, banks 3-6 contain DSP code and data,
|
||||
and banks 8-14 seem to contain factory default settings. There are flash
|
||||
programming routines at the beginning of banks 7 and 15, and two at the
|
||||
end of bank 6. Not sure why there are so many, and not all are
|
||||
identical, so there's probably additional bank swithing logic to match.
|
||||
All display a charming "DO NOT TOUCH ME" message while programming. :)
|
||||
|
||||
The same bank switching also seems to affect external memory, but I'm
|
||||
not sure how the smaller SRAM is mapped. Some external memory locations
|
||||
are used for other tasks, like communicatng with the DSP.
|
||||
|
||||
The initial DSP program and data upload routine is at 0x1FAA. After
|
||||
setting up the bus, it churns out all the 24-bit words in banks 3-6
|
||||
(except for headers) as one stream. The DSP will interpret the first
|
||||
word as a length, the second as address, and the following "length"
|
||||
words will be stored at that address in program memory before execution
|
||||
starts there. This is just a very short bootstrap program, which takes
|
||||
care of receiving the remaining words in chunks. Each chunks starts with
|
||||
three words - a command, an address, and optionally length. Commands 0-2
|
||||
store data in P, X, or Y memory respectively. Command 3 splits each
|
||||
24-bit word into two 12-bit values and store each of them as a 24-bit
|
||||
word in Y memory. Command 4 starts execution at the specified address,
|
||||
and doesn't have a length.
