GENERAL DESCRIPTION
The ADSP-2136x SHARC
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 (sin-
gle-instruction, single-data) mode. The ADSP-2136x is a
performance automotive audio applications with 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
ADSP-2136x uses two computational units to deliver a signifi-
cant performance increase over the previous SHARC processors
on a range of signal processing algorithms. Fabricated in a state-
of-the-art, high speed, CMOS process, the ADSP-2136x proces-
sor achieves an instruction cycle time of 3.0 ns at 333 MHz.
With its SIMD computational hardware, the ADSP-2136x can
perform two GFLOPS running at 333 MHz.

The ADSP-2136x continues SHARC’s industry-leading stan-
dards of integration for DSPs, combining a high performance
32-bit DSP core with integrated, on-chip system features.
