Overview
The ADSP-21369KSWZ-2A, produced by Analog Devices Inc., is a member of the third generation of SHARC (Super Harvard Architecture) processors. This 32-bit/40-bit floating-point digital signal processor (DSP) is optimized for high-performance applications, particularly in automotive audio and other demanding signal processing tasks. The ADSP-21369 features a SIMD (Single Instruction, Multiple Data) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats. It is source code-compatible with previous SHARC processors, allowing for maximum reuse of legacy code. The processor operates at a frequency of 400 MHz and achieves a peak performance of 2.4 GFLOPS.
