TMS320C6657 - Fixed and Floating-Point Digital Signal Processor

Download the TMS320C6657 datasheet PDF. This datasheet also covers the TMS320C6655 variant, as both devices belong to the same fixed and floating-point digital signal processor family and are provided as variant models within a single manufacturer datasheet.

General Description

The C665x are high performance fixed- and floating-point DSPs that are based on TI's KeyStone multicore architecture.

Incorporating the new and innovative C66x DSP core, this device can run at a core speed of up to 1.25 GHz.

Key Features

  • 1.
  • One (C6655) or Two (C6657) TMS320C66x™ DSP Core Subsystems (CorePacs), Each With.
  • 850 MHz (C6657 only), 1.0 GHz, or 1.25 GHz C66x Fixed- and Floating-Point CPU Core.
  • 40 GMAC per Core for Fixed Point @ 1.25 GHz.
  • 20 GFLOP per Core for Floating Point @ 1.25 GHz.
  • Multicore Shared Memory Controller (MSMC).
  • 1024KB MSM SRAM Memory (Shared by Two DSP C66x CorePacs for C6657).
  • Memory Protection Unit for Both MSM SRAM and DDR3_EMIF.
