ADSP-21488BSWZ-3A

Digital Signal Processor Dsp Overview

The ADSP-21488BSWZ-3A is a 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for high-performance audio processing. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements (PEX and PEY). The device operates at a maximum instruction rate of 400 MHz and includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. It utilizes Analog Devices’ Super Harvard Architecture to eliminate I/O bottlenecks. The processor supports IEEE 32-bit single-precision and 40-bit extended precision floating-point formats, alongside 32-bit fixed-point data.
