DSP-96
The DSP-96 was the second board I designed at Ariel Corporation using
the Motorola DSP96002 chip (the first was the dual-processor
MM-96). If memory serves me this was introduced around
1991. It was also the first board Ariel made with a daughter card
expansion system to support different kinds of I/O within one PC
slot. The A/D/A daughter card featured these terrible Motorola
sigma-delta converters, hopless beasts with idle tones and no better
than 90dB SNR. The 32 bit address/data expansion was neat - it
had arbitration and tied one memory bus of the DSP96002 together across
up to 4 board to create a large pool of shared memory.
Features:
- 33MHz DSP96002
- Full-speed 16-bit ISA bus with DMA support
- 1 bank up to 64MB DRAM
- 2 banks of 256KB zero-wait state SRAM
- Daughter card I/O
- Stereo 16-bit A/D/A converters
- DSP-Port
- Parallel 8-bit video expansion port
- Parallel 16-bit general purpose expansion port
- 32 bit expansion address/data bus
