    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

    DSP
  • Motorola DSP56002 @ 37 (underclocked 40 MHz) or 73.7 MHz (overclocked from 66 MHz)
  • 24 bit data bus
  • fully programmable using the supplied software
    memory
  • 96 kB, 24 bit SRAM
  • one half of the memory can be addressed in program and X data space, the other half only in Y data space
  • zero-waitstate, 12 ns
    audio
  • Crystal CS4231A audio codec
  • one stereo RCA input
  • one stereo 3.5 mm input with optional 20 dB mic amplifier
  • one internal CD-ROM input
  • one stereo RCA output
  • all inputs can be mixed with Delfina's output
  • full duplex recording and playback
  • AHI support
    notes
  • connects to the clock port
  • the audio cables are connected directly onto the board, not to the back of the Amiga

    DSP
  • Motorola DSP56002 @ 67.73 MHz (overclocked from 66 MHz)
  • 24 bit data bus
    memory
  • 96 kB, 24 bit SRAM, not expandable
  • zero-waitstate, 12 ns
    audio
  • sample frequencies up to 48 kHz at 16 bit
  • unlike previous Delfinas, other frequencies are played back without resampling, freeing up DSP resources
  • three stereo inputs with regular intensity
  • one stereo input with increased sensitivity for a microphone
  • one stereo output (RCA)
  • full duplex recording and playback
  • AHI driver
    Delfina module
  • carries the DSP, memory and the analog inputs and outputs
  • can be connected to the clock port of the A1200, or to the 26 pin expansion port that is available on all Individual Computer's cards
    • clock port pin 40 is marked
    optional Flipper module
  • simply attaches to the Delfina module
  • expands the Delfina with digital SP-DIF connectors
  • MIDI In and MIDI Out connectors - can be programmed independently of each other
  • Zorro II and PCI connectors

    DSP
  • Motorola DSP56002 @ 40 MHz
  • 24 bit data bus - 24 dB dynamic range
  • fully programmable using the supplied software
    memory
  • 96 kB, 24 bit SRAM, not expandable
  • one half of the memory can be addressed in program and X data space, the other half only in Y data space
  • zero-waitstate, 12 ns
    audio
  • Crystal CS4231A audio codec
  • sample frequencies up to 48 kHz at 16 bit
  • three stereo inputs (2 RCA, 1 internal CD-ROM), one stereo output (RCA)
  • all inputs can be mixed with Delfina's output
  • full duplex recording and playback
  • AHI driver
    optional serial interface module - DelfSer
  • connects to Delfina's expansion connector (DelfExp)
  • maximum serial speed is 625000 bps (1/64th of the DSP clock rate)
  • lower speeds are generated by dividing the maximum speed by an integer
  • DB25 serial connector
  • can be ordered with 100% Amiga compatible serial port - including -12V and +12V power - otherwise these signals are simply cut
  • allocates a buffer of its own in Delfina's memory, so using DelfSer may disable some memory hungry DSP effects
  • a 24 bit S/PDIF digital I/O was also planned for DelfExp, but never released
    notes
  • 8 bit Zorro bus interface logic - when running many sound outputting programs at the same time, the system may feel slow responding
