Overview
The TMS320C6722B, produced by Texas Instruments, is a high-performance 32-/64-bit floating-point digital signal processor (DSP) belonging to the C67x generation. This device is part of the next generation of TI's C67x DSPs, which include the TMS320C6727B, TMS320C6726B, TMS320C6722B, and TMS320C6720. The C6722B is designed to offer significant improvements in speed, code density, and floating-point performance compared to its predecessors.
At a clock speed of up to 350 MHz, the C6722B achieves a maximum performance of 2800 MIPS and 2100 MFLOPS, executing up to eight instructions per cycle, six of which can be floating-point instructions. This makes it highly suitable for demanding applications requiring high computational power and efficiency.
