The third generation of SHARC(R) Processors offers increased performance, audio and application-focused peripherals, and new memory configurations. The ADSP-21368 increases performance to 400MHz while simplifying algorithm development with the integration of a high-bandwidth and very flexible external memory interface. The ADSP-21368 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-21368 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-21368 maximizes system throughput while minimizing system bill of materials costs.
The ADSP-21368 also provides hardware support for connection multiple processors to a single, shared external memory array. The support includes:
第三代SHARC(R)处理器提供了更高的性能、以音频功能和应用为重点的外设以及新型存储器配置。ADSP21368将性能提升至400MHz,并通过集成一个高带宽且非常灵活的外部存储器接口简化了算法的开发。ADSP-21368基于一个单指令、多数据(SIMD)内核(该内核支持32位定点和32/40位浮点算术格式),且代码与先前推出的所有SHARC处理器完全兼容,从而为实现传统代码的最大限度重用奠定了基础。ADSP-21368将片上存储器的数量增加至2Mb SRAM和6Mb ROM,同时集成了各种音频专用和通用型外设。外设(比如:一个全数字S/PDIF发送器/接收器、8通道异步采样频率转换器、8个高速串行端口、4个精密时钟发生器以及多个串行接口等)的组合确保了ADSP-21368能够在最大限度地降低系统材料成本的同时实现系统吞吐量的最大化。ADSP-21368还为将多个处理器连接至一个共享外部存储器阵列提供了硬件支持。这种支持包括:
