Enhanced C67x+ CPU

        The C67x+ CPU is an enhanced version of the C67x CPU used on the DA6xxx first-generation Aureus™ DSP. It is compatible with the C67x CPU but offers significant improvements in speed, code density, and floating-point performance per clock cycle.

        At 250 MHz, the CPU is capable of a maximum performance of 2000 MIPS/1500 MFLOPS by executing up to eight instructions (six of which are floating-point instructions) in parallel each cycle. The CPU natively supports 32-bit fixed-point, 32-bit single-precision floating-point, and 64-bit double-precision floating-point arithmetic.
