ABSTRACT:
A controller has a data compression unit and error correcting code unit which share a single common random access memory. The controller is connected between a host computer and a peripheral device such as a tape drive. A second order search for strings of data bytes is enabled or disabled to change the compression ratio, data throughput, and memory bandwidth constraints.
