Description

The ADSP-TS203S TigerSHARC processor is an ultra-high per- formance, static superscalar processor optimized for large signal processing tasks and communications infrastructure. The DSP combines very wide memory widths with dual computation  blockssupporting 32- and 40-bit floating-point and support ing 8-, 16-, 32-, and 64-bit fixed-point processingto set a new standard of performance for digital signal processors. The  TigerSHARC static superscalar architecture lets the DSP exe- cute up to four instructions each cycle, performing twenty-four 16-bit fixed-point operations or six floating-point operations.

Four independent 128-bit wide internal data buses, each con- necting to the four 1Mbit memory banks, enable quad-word  data, instruction, and I/O accesses and provide 28Gbytes per  second of internal memory bandwidth. Operating at 500MHz,  the ADSP-TS203S processors cor has a 2.0ns instruction cycle time. Using its Single-Instruction, Multiple-Data (SIMD) fea- tures, the ADSP-TS203S processor can perform four billion 40- bit MACs or one billion 80-bit MACs per second.
