Overview
The ADSP-TS101S TigerSHARC processor, manufactured by Analog Devices Inc., is an ultrahigh performance, Static Superscalar processor. It is optimized for large signal processing tasks and communications infrastructure. This DSP combines wide memory widths with dual computation blocks, supporting various bit-widths for floating-point and fixed-point processing. The processor operates at 300 MHz with a 3.3 ns instruction cycle time and can execute up to four instructions per cycle, performing 24 fixed-point (16-bit) operations or six floating-point operations. It features single-instruction, multiple-data (SIMD) capabilities, enabling high-performance MAC operations.
