High Precision 32-Bit Floating-Point SHARC Processor for Professional Audio

The ADSP-2136x SHARC® processor is a member of the SIMD SHARC family of DSPs that feature Analog Devices, Inc., Super Harvard Architecture. The processor is 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 ADSP-2136x are 32-/40-bit floating-point processors optimized for high performance automotive audio applications. They contain a large on-chip SRAM and ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital audio interface (DAI).

As shown in the functional block diagram on Page 1, the ADSP-2136x uses two computational units to deliver a significant performance increase over the previous SHARC processors on a range of signal processing algorithms. With its SIMD computational hardware, the ADSP-2136x can perform two GFLOPS running at 333 MHz.
