Digital Video Processor
For my senior project at Caltech,
I built a digital video processor capable of displaying real-time
color video on the sides of spinning cube.
My final report on the video processor contains
a theory of operation, a description of its capabilities, and a discussion
of the problems I encountered while building it.
I used Quinn Jensen's
public domain DSP56001 assembler to develop the software for this project.
The main subsystems are
- A Phillips SAA9091 Digital Multi-Standard Decoder that
digitizes color analog video
- A bank of 12 256K x 4 VRAMs that stores two full-color frames
- A Motorola DSP56001 Digital Signal Processor that controls
the flow of video into the framebuffers
- A Phillips SAA7192 Digital Color-Space Converter coupled with
a Brooktree Bt101 Video DAC that drives an analog RGB monitor
6 pages of schematics in PDF format.
The systemwide timing diagram
is also available.
