Abstract

This relates to a general purpose circuit that maximizes the computing power of a Unix workstation or other computer system for processing image or other data in accordance with a selected one or ones of several alternative compression and decompression algorithms. This dynamically allocates system memory for storage of both compressed and uncompressed data and ensures adequate compression and decompression rates.
