TMS320C66x
High-Performance
Multicore DSP
Based on TI’s innovative KeyStone architecture, the new TMS320C66x DSP core and generation of C66x multicore devices include the
industry’s first 10-GHz DSP with 320 GMACs and 160 GFLOPs of combined fixed- and floating-point performance on a single device. These
devices are designed to maximize the throughput of on-chip data flows and eliminate the possibility of bottlenecks. This enables developers to
fully utilize the vast processing power of the DSP cores to design applications in markets such as test and measurement, mission critical,
industrial automation, medical and high-end imaging equipment, and high-performance computing.
