ADSP-21479

Overview

The ADSP-21479 is a high-performance 32-bit floating-point Digital Signal Processor (DSP) from the SHARC family, operating at up to 266MHz. It features a large 5Mbit on-chip RAM and 4Mbit of internal ROM, making it well-suited for memory-intensive signal processing tasks without external memory overhead. The processor includes dedicated hardware for audio processing, such as S/PDIF interfaces and a Digital Applications Interface (DAI).

Why Choose This Part

The ADSP-21479 offers a significant amount of integrated memory with 5Mbit of RAM, reducing the complexity of PCB routing for external memory. Its SHARC core supports SIMD (Single-Instruction, Multiple-Data) operations, which doubles the performance for signal processing algorithms compared to traditional RISC processors. The device integrates specialized peripherals like a Digital Applications Interface (DAI) and hardware-based S/PDIF for seamless audio integration.

Applications

Getting Started

Development is primarily supported through Analog Devices CrossCore Embedded Studio (CCES) and the VisualDSP++ environment. Engineers can utilize the ADZS-21479-EZLITE evaluation board to prototype audio and signal processing applications. Hardware debugging is handled via the integrated 14-pin JTAG header using an ICE-1000 or ICE-2000 emulator.
