ADSP-SC570/SC571/SC572/SC573/ADSP-21571/21573
GENERAL DESCRIPTION
The ADSP-SC57x/ADSP-2157x processors are members of the
SHARC
®
family of products. The ADSP-SC57x processor is
based on the SHARC+
®
dual-core and the ARM
®
Cortex
®
-A5
core. The ADSP-SC57x/ADSP-2157x SHARC processors are
members of the single-instruction, multiple data (SIMD)
SHARC family of digital signal processors (DSPs) that feature
Analog Devices Super Harvard Architecture. These 32-bit/40-
bit/64-bit floating-point processors are optimized for high per-
formance audio/floating-point applications with large on-chip
static random-access memory (SRAM), multiple internal 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 prediction, while
maintaining instruction set compatibility to previous SHARC
products.
By integrating a set of industry leading system peripherals and
memory (see
Table 1, Table 2,
and
Table 3),
the ARM Cortex-
A5 and SHARC processor is the platform of choice for applica-
tions that require programmability similar to reduced
instruction set computing (RISC), multimedia support, and
leading edge signal processing in one integrated package. These
applications span a wide array of markets, including automo-
tive, professional audio, and industrial-based applications that
require high floating-point performance.
