Amiga Hardware DatabaseManufacturer Petsoff, Finland | Date 1996 | Amiga A2000, A3000, A4000 | Interface Zorro II | Autoconfig ID 14501 / 0 |
- DSP
- Motorola DSP56002 @ 40 MHz
- 24 bit data bus
- 56 bit accumulators
- most instructions executed in one cycle
- fully programmable
- memory
- 96 kB, 24 bit SRAM, expandable to 192 or 384 kB
- dual ported, addressable by both the DSP and Amiga - when the Amiga is accessing the memory at full speed, DSP is slowed down by 10% maximum
- one half of the memory can be addressed in program and X data space, the other half only in Y data space
- zero-waitstate, 25 ns
- audio
- Crystal CS4215 audio codec connected directly to the DSP's serial bus
- 16 bit stereo digitizing and multichannel playback at 50 kHz
- sample frequencies up to 50 kHz
- 16 or 8 bit linear, µ-law or A-law audio data coding
- programmable gain and attenuation
- microphone and line level inputs
- headphone and line level outputs
- on-chip anti-aliasing/smoothing filters
- AHI driver
- I/O
- one of the DSP's serial port is for the audio codec, the other is used for RS232
- all remaining I/O lines are used for the parallel port
- serial baud rate is internally divided from 625000 bps, delfser.device rounds the requested baudrate to the closest available rate - setting a rate of 115200 results in 125000 bps
- MIDI rate 31250 matches exactly, with a divider of 20
- parallel port is similar to the Amiga's port, just used by delfpar.device
- DB9 serial connector
- DB25 Centronics parallel interface
