General Description

The TMS320C82 is a single chip, MIMD (multiple instruction/multiple data) parallel processor capable of performing over 1.5 billion operations per second.

It consists of a 32-bit RISC Master Processor with a 120-MFlop IEEE Floating Point Unit, two 32-bit parallel-processing DSPs (PPs), and a Transfer Controller with up to 480 Mbyte/sec transfer rate.

All the processors are tightly coupled via an on-chip crossbar which provides shared access to on-chip RAM.
