GENERAL DESCRIPTION

The ADSP-21065L is a powerful member of the SHARC family of 32-bit processors optimized for cost sensitive applications. The SHARC—Super Harvard Architecture—offers the highest levels of performance and memory integration of any 32-bit DSP in the industry—they are also the only DSP in the industry that offer both fixed and floating-point capabilities, without compromising precision or performance.
