The third generation of SHARC® 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:
- Distributed, on-chip arbitration for the shared external bus
- Fixed and rotating priority bus arbitration
- Bus timeout logic
- Bus lock
