GENERAL DESCRIPTION
The ADSP-21367/ADSP-21368/ADSP-21369 SHARC® processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. These processors are source code-compatible with the ADSP-2126x and ADSP-2116x DSPs as well as with first generation ADSP-2106x SHARC processors in SISD (single-instruction, single-data) mode. The processors are 32-bit/40-bit floating-point processors optimized for high performance automotive audio applications with its large on-chip SRAM, mask programmable ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI).

SUMMARY
   High performance 32-bit/40-bit floating-point processor
      optimized for high performance audio processing
   Single-instruction, multiple-data (SIMD) computational
      architecture
   On-chip memory—2M bits of on-chip SRAM and 6M bits of
      on-chip mask programmable ROM
   Code compatible with all other members of the SHARC family
   The ADSP-21367/ADSP-21368/ADSP-21369 are available
      with a 400 MHz core instruction rate with unique
      audiocentric peripherals such as the digital applications interface,
      S/PDIF transceiver, serial ports, 8-channel asynchronous
      sample rate converter, precision clock generators, and
      more. For complete ordering information, see Ordering
      Guide.
