GENERAL DESCRIPTION

The ADSP-TS101S TigerSHARC® processor is an ultrahigh performance, Static SuperscalarTM †processor optimized for large signal processing tasks and communications infrastructure. The DSP combines very wide memory widths with dual computation blocks—supporting 32- and 40-bit floating-point and 8-, 16-, 32-, and 64-bit fixed-point processing—to set a new standard of performance for digital signal processors. The TigerSHARC processor’s Static Superscalar architecture lets the processor execute up to four instructions each cycle, performing 24 fixed-point (16-bit) operations or six floating-point operations.
