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. This performance and programmability make the ‘C82 ideally
suited for video, imaging, and high-speed telecommunication applications.
