第三代SHARC®处理器提供了更高的性能、以音频和应用为重点的外设和新的存储器配置。ADSP-21369的性能提升至400MHz,同时简化了算法开发并集成了高带宽和非常灵活的外部存储器接口。ADSP-21369基于一个单指令多数据(SIMD)内核,支持32位定点和32-/40位浮点运算格式,与以前的所有SHARC处理器代码完全兼容,可最大化地复用已有代码。ADSP-21369的片上存储器总数增加到2MB的SRAM和6M ROM,同时集成了各种音频专用和通用外设。多种片上外设如一个全数字化S / PDIF发射器/接收器、8通道异步采样率转换器、8个高速串行端口、4个精密时钟发生器以及多种串行接口相结合,可确保ADSP-21369实现最大的系统吞吐量,并将材料成本减至最低。
The third generation of SHARC® Processors offers increased performance, audio and application-focused peripherals, and new memory configurations. The ADSP-21369 increases performance to 400MHz while simplifying algorithm development with the integration of a high-bandwidth and very flexible external memory interface. The ADSP-21369 is based on a single-instruction, multiple-data (SIMD) core which supports both 32-bit fixed-point and 32-/40-bit floating point arithmetic formats and is completely code-compatible with all prior SHARC Processors allowing for maximum reuse of legacy code.
The ADSP-21369 increases the amount of on-chip memory to 2Mb SRAM and 6Mb ROM while integrating a variety of audio-specific and general purpose peripherals. Peripherals such as an all digital S/PDIF transmitter/receiver, 8-channel asynchronous sample rate converter, 8 high-speed serial ports, 4 precision clock generators, and multiple serial interfaces combine to ensure the ADSP-21369 maximizes system throughput while minimizing system bill of materials costs.
