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

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 @ 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
