ANDI-FG PC-104 Video Digitizer


The ANDI-FG board is a 24-bit digitizer on a PC-104 board based around a Motorola 56001 DSP and a Phillip's digitizing chipset. It comes with a library to take pictures and upload them over the pc104 bus to the host system, but it's possible to download user-supplied code to the DSP and perform image processing on the board itself. This both frees the system's main cpu for other tasks, and eliminates the time consuming process of downloading the image over a relatively slow 8-bit pc104 bus.

Technical Notes

These are my own notes on the ANDI-FG board, and supplement the supplied documentation.

Software

Eventually I'll place some example code here, once it's been written. I'm developing programs using the assembler and linker that came with Black NeXT hardware (NeXT machines used a 56001 in their sound hardware) If you're lucky enough to have access to one of these systems, try 'asm56000' and 'lnk56000'.
