Overview
The ADSP-21160MKBZ-80 is a high-performance Digital Signal Processor (DSP) from Analog Devices Inc., part of the SHARC family. This processor is optimized for various high-demand applications such as telephony, medical imaging, radar/sonar electronics, communications, and 3D graphics and imaging. The ADSP-21160M features a Single-Instruction-Multiple-Data (SIMD) architecture, which significantly enhances its processing capabilities compared to earlier models like the ADSP-2106x. It is code compatible with the first generation ADSP-2106x SHARC DSPs, making it easier to port existing code while leveraging the new SIMD capabilities.
