Product Overview
The TMS320C6657CZHA is a high-performance dual-core digital signal processor (DSP) from Texas Instruments, built on the KeyStone multicore architecture. Featuring two TMS320C66x DSP CorePacs operating at up to 1.25 GHz, this device delivers industry-leading fixed- and floating-point performance with 40 GMAC per core for fixed-point operations and 20 GFLOP per core for floating-point computations.
Packaged in a 625-pin flip-chip BGA (CZH) measuring 21 mm × 21 mm, the C6657 integrates a rich set of high-speed peripherals including Serial RapidIO 2.1 (4 lanes), PCI Express Gen2, HyperLink, Gigabit Ethernet, DDR3-1333 memory controller, and a 16-bit EMIF. The Multicore Navigator with 8192 hardware queues enables zero-overhead data transfers, while the on-chip hardware accelerators (VCP2, TCP3d) offload Viterbi and Turbo decoding operations.
Characterized for extended temperature operation from –40°C to 100°C, the TMS320C6657CZHA is fully backward compatible with all existing C6000 family fixed- and floating-point DSPs, ensuring software portability and reduced development cycles.
