5. External System RAM: This ASIC supports 256k*16, 1M*16, 2M*16,
and 4M*16 EDO DRAMs for storing shading, gamma tables, and
buffering data to transmit to host PC.
6. Host I/O interface: Connect to host PC via SCSI.
7. Digital signal processing: even-odd compensation, digital shading,
1-D LPF, Gamma correction, binary image processing.
8. A horizontal resolution control (by decimation) circuit.
9. An 16-bit Misc. I/O port for connecting motor driver, LEDs, sensors,
etc..
