|
Capcom System QSound™
|
||||||
=====================
|
|
||||||
|
|
||||||
Driver by Paul Leaman and Miguel Angel Horna
|
Sixteen-channel sample player. Previous HLE implementation by Paul
|
||||||
|
Leaman and Miguel Angel Horna, with thanks to CAB (author of Amuse).
|
||||||
|
|
||||||
A 16 channel stereo sample player.
|
The key components are a DSP16A, a TDA1543 dual 16-bit DAC with I2S
|
||||||
|
input, and a TC9185P electronic volume control. The TDA1543 is
|
||||||
|
simulated here; no attempt is being made to emulate theTC9185P.
|
||||||
|
|
||||||
QSpace position is simulated by panning the sound in the stereo space.
|
Commands work by writing an address/data word pair to be written to
|
||||||
|
DSP's internal RAM. In theory it's possible to write anywhere in
|
||||||
|
DSP RAM, but the glue logic only allows writing to the first 256
|
||||||
|
words. The host writes the high and low bytes the data word to
|
||||||
|
offsets 0 and 1, respectively, and the address to offset 2. Writing
|
||||||
|
the address also asserts the DSP's INT pin. The host can read back
|
||||||
|
a single bit, which I've assumed reflects the current state of the
|
||||||
|
DSP's INT pin (low when asserted). The host won't send further
|
||||||
|
commands until this bit goes high.
|
||||||
|
|
||||||
Many thanks to CAB (the author of Amuse), without whom this probably would
|
On servicing an external interrupt, the DSP reads pdx0 three times,
|
||||||
never have been finished.
|
expecting to get the address and data in that order (the third read
|
||||||
|
is needed because DSP16 has latent PIO reads in active mode). I've
|
||||||
|
assumed that reading PIO with PSEL low when INT is asserted will
|
||||||
|
return the address and cause INT to be de-asserted, and reading PIO
|
||||||
|
with PSEL low when int is not asserted will return the data word.
|
||||||
|
|
||||||
TODO:
|
The DSP program uses 2 kilowords of internal RAM and reads data from
|
||||||
- hook up the DSP!
|
external ROM while executing from internal ROM. As such, it
|
||||||
- is master volume really linear?
|
requires a DSP16A core (the original DSP16 only has 512 words of
|
||||||
- understand higher bits of reg 0
|
internal RAM and can't read external ROM with internal ROM enabled).
|
||||||
- understand reg 9
|
|
||||||
- understand other writes to $90-$ff area
|
To read external ROM, the DSP writes the desired sample offset to
|
||||||
|
PDX0, then reads external ROM at address (bank | 0x8000), for a
|
||||||
|
theoretical maximum of 2 gigasamples. The bank applies to the next
|
||||||
|
read, not the current read. A dummy read is required to set the
|
||||||
|
bank for the very first read. This latency could just be a quirk of
|
||||||
|
how Capcom hooks the DSP up to the sample ROMs. In theory, samples
|
||||||
|
are 16-bit signed values, but Capcom only has 8-bit ROMs connected.
|
||||||
|
I'm assuming byte smearing, but it may be zero-padded in the LSBs.
|
||||||
|
|
||||||
|
The DSP sends out 16-bit samples on its SIO port clocked at 2.5 MHz.
|
||||||
|
The stereo samples aren't loaded fast enough for consecutive frames
|
||||||
|
so there's an empty frame between them. Sample pairs are loaded
|
||||||
|
every 1,248 machine cycles, giving a sample rate of 24.03846 kHz
|
||||||
|
(60 MHz / 2 / 1248). It's unknown how the real hardware identifies
|
||||||
|
left/right samples - I'm using a massive hack at the moment.
|
||||||
|
|
||||||
|
The DSP writes values to pdx1 every sample cycle (alternating
|
||||||
|
between zero and non-zero values). This may be for the volume
|
||||||
|
control chip or something else.
|
||||||
|
|
||||||
|
The photographs of the DL-1425 die (WEDSP16A-M14) show 12 kilowords
|
||||||
|
of internal ROM compared to 4 kilowords as documented. It's unknown
|
||||||
|
if/how the additional ROM is mapped in the DSP's internal ROM space.
|
||||||
|
The internal program only uses internal ROM from 0x0000 to 0x0fff
|
||||||
|
and external space from 0x8000 onwards. The additional ROM could
|
||||||
|
be anywhere in between.
|
||||||
|
|
||||||
|
Meanings for known command words (0x00 to 0x8f mostly understood):
|
||||||
|
(((ch - 1) << 3) & 0x78 sample bank
|
||||||
|
(ch << 3) | 0x01 current/starting sample offset
|
||||||
|
(ch << 3) | 0x02 rate (zero for key-off)
|
||||||
|
(ch << 3) | 0x03 key-on
|
||||||
|
(ch << 3) | 0x04 loop offset (relative to end)
|
||||||
|
(ch << 3) | 0x05 end sample offset
|
||||||
|
(ch << 3) | 0x06 channel volume
|
||||||
|
ch | 0x80 position on sound stage
|
||||||
|
|
||||||
|
The games don't seem to use (ch << 3) | 0x07 for anything. The
|
||||||
|
games use 0xba to 0xcb, but the purpose is not understood.
|
||||||
|
|
||||||
|
The weird way of setting the sample bank is due to the one-read
|
||||||
|
latency described above. Since the bank applies to the next read,
|
||||||
|
you need to set it on the channel before the desired channel.
