Overview
The TMS320C6727BGDH300 is a high-performance 32-/64-bit floating-point digital signal processor (DSP) from Texas Instruments, part of the C67x generation. This device is an enhanced version of the C67x CPU used in the C671x DSPs, offering significant improvements in speed, code density, and floating-point performance per clock cycle. At a clock speed of up to 350 MHz, the CPU can achieve a maximum performance of 2800 MIPS and 2100 MFLOPS, executing up to eight instructions (six of which are floating-point instructions) in parallel each cycle. The TMS320C6727B is designed for demanding applications requiring high computational power and efficient memory management.
