Overview
The TMS320C6654CZH8 is a high-performance fixed- and floating-point digital signal processor (DSP) from Texas Instruments, based on the KeyStone multicore architecture. This device is part of the C665x family and is designed to offer exceptional computational power and low power consumption. The C6654 DSP features a single C66x core, which operates at up to 850 MHz, providing industry-leading performance in signal processing, mathematical, and image acquisition functions.
The processor is backward code-compatible with TI's previous generation C6000 fixed- and floating-point DSP cores, ensuring software portability and shortened software development cycles. It also integrates a significant amount of on-chip memory, including 32KB of L1 program and data cache, and 1024KB of dedicated L2 memory that can be configured as mapped RAM or cache.
