Yamaha YMZ280B driver

|
|

YMZ280B 8-Channel PCMD8 PCM/ADPCM Decoder
|
||||||
|
|
||||||
|
Features as listed in LSI-4MZ280B3 data sheet:
|
||||||
|
Voice data stored in external memory can be played back simultaneously for up to eight voices
|
||||||
|
Voice data format can be selected from 4-bit ADPCM, 8-bit PCM and 16-bit PCM
|
||||||
|
Control of voice data external memory
|
||||||
|
Up to 16M bytes of ROM or SRAM (x 8 bits, access time 150ms max) can be connected
|
||||||
|
Continuous access is possible
|
||||||
|
Loop playback between selective addresses is possible
|
||||||
|
Voice data playback frequency control
|
||||||
|
4-bit ADPCM ................ 0.172 to 44.1kHz in 256 steps
|
||||||
|
8-bit PCM, 16-bit PCM ...... 0.172 to 88.2kHz in 512 steps
|
||||||
|
256 steps total level and 16 steps panpot can be set
|
||||||
|
Voice signal is output in stereo 16-bit 2's complement MSB-first format
|
||||||
|
|
||||||
|
TODO:
|
||||||
|
- Is memory handling 100% correct? At the moment, Konami firebeat.c is the only
|
||||||
|
hardware currently emulated that uses external handlers.
|
||||||
|
It also happens to be the only one using 16-bit PCM.
|
||||||
|
|
||||||
|
Some other drivers (eg. bishi.cpp, bfm_sc4/5.cpp) also use ROM readback.
