GENERAL DESCRIPTION
The ADSP-21061 is a member of the powerful SHARC family of floating point processors. The SHARC—Super Harvard Architecture Computer—are signal processing microcomputers that offer new capabilities and levels of integration and performance. The ADSP-21061 is a 32-bit processor optimized for high performance DSP applications. The ADSP-21061 combines the ADSP-21000 DSP core with a dual-ported on-chip SRAM and an I/O processor with a dedicated I/O bus to form a complete system-in-a-chip.
