ADI公司的ADSP-21469是第四代SHARC处理器,提供最高的性能450 MHz/2700 MFLOPs以及基于硬件的增强性能FIR,IIR和FFT滤波器加速器,音频和基于应用的外设,支持最新环绕声译码器算法的存储器配置,内核工作频率450MHz,片上5Mb RAM,特别适合于DOLBY® ATMOS影院环绕声译码的家庭影院.本文介绍了ADSP-21469主要特性和优势,框图, SHARC内核框图,以及SHARC 21469 EZ-KIT Lite 评估板主要特性,系统架构图,电路图和材料清单.

The fourth generation of SHARC® Processors, which includes the ADSP-21469, offers increased performance, hardware-based filter accelerators, audio and application-focused peripherals, and new memory configurations capable of supporting the latest surround-sound decoder algorithms. All devices are pin-compatible with each other and completely code-compatible with all prior SHARC Processors. These newest members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.
