Product Introduction

Overview

The TMS320C6726B, part of the TMS320C672x family, is a high-performance 32-/64-bit floating-point digital signal processor (DSP) from Texas Instruments. This DSP is an enhanced version of the C67x generation, offering significant improvements in speed, code density, and floating-point performance. The C6726B is designed for applications requiring high computational power and efficient memory management.

The C6726B operates at a maximum frequency of 266 MHz, although the C672x family can reach up to 350 MHz. It features the enhanced C67x+ CPU, which supports 32-bit fixed-point, 32-bit single-precision floating-point, and 64-bit double-precision floating-point arithmetic. This CPU can execute up to eight instructions per cycle, with six of these being floating-point instructions, resulting in maximum performance of 2800 MIPS and 2100 MFLOPS at 350 MHz.
