ADSP-21591/21593/21594/ADSP-SC591/SC592/SC594 Preliminary Technical Data

GENERAL DESCRIPTION

The ADSP-2159x/ADSP-SC59x processors are members of the

SHARC

® family of products. The ADSP-SC59x processors are

based on the SHARC+® dual-core and the Arm® Cortex®-A5

core. The ADSP-2159x/ADSP-SC59x SHARC processors are

members of the single-instruction, multiple data (SIMD)

SHARC family of digital signal processors (DSPs) that feature

Analog Devices, Inc., Super Harvard Architecture. These 32-

bit/40-bit/64-bit floating-point processors are optimized for

high performance audio/floating-point applications with large

on-chip static random-access memory (SRAM), multiple inter-

nal buses that eliminate input/output (I/O) bottlenecks, and

innovative digital audio interfaces (DAI). New additions to the

SHARC+ core include cache enhancements and branch predic-

tion, while maintaining instruction set compatibility to previous

SHARC products.

By integrating a set of industry leading system peripherals and

memory, the Arm Cortex-A5 and SHARC processor is the plat-

form of choice for applications that require programmability

similar to reduced instruction set computing (RISC), multime-

dia support, and leading edge signal processing in one

integrated package. These applications span a wide array of

markets, including automotive, professional audio, and indus-

trial-based applications that require high floating-point

performance.

Table 1 provides comparison information for features that vary

across the standard processors.
