ADSP-2106x SHARC® DSP Microcomputer Family

GENERAL DESCRIPTION

The ADSP-21061 SHARC—Super Harvard Architecture Computer—is a signal processing microcomputer that offers new capabilities and levels of performance. The ADSP-21061 SHARC is a 32-bit processor optimized for high performance DSP applications. The ADSP-21061 builds on the ADSP-21000 DSP core to form a complete system-on-a-chip, adding a dualported on-chip SRAM and integrated I/O peripherals supported by a dedicated I/O bus.

SUMMARY
