1.3 Description
The C665x are high performance fixed- and floating-point DSPs that are based on TI's KeyStone multicore
architecture. Incorporating the new and innovative C66x DSP core, this device can run at a core speed of
up to 1.25 GHz. For developers of a broad range of applications, both C665x DSPs enable a platform that
is power-efficient and easy to use. In addition, the C665x DSPs are fully backward compatible with all
existing C6000™ family of fixed- and floating-point DSPs.
