GENERAL DESCRIPTION

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).

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—3M bits of on-chip SRAM

Code compatible with all other members of the SHARC family

The ADSP-2136x processors are available with up to 333 MHz

core instruction rate with unique audiocentric peripherals

such as the digital applications interface, S/PDIF transceiver, DTCP (digital transmission content protection

protocol), serial ports, precision clock generators, and

more. For complete ordering information, see Ordering

Guide on Page 54.
