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
