GENERAL DESCRIPTION
The ADSP-21160M SHARC DSP is the first processor in
a new family featuring Analog Devices’ Super Harvard
Architecture. Easing portability, the ADSP-21160M is
application source code compatible with first generation
ADSP-2106x SHARC DSPs in SISD (Single Instruction,
Single Data) mode. To take advantage of the processor’s
SIMD (Single Instruction, Multiple Data) capability, some
code changes are needed. Like other SHARCs, the
ADSP-21160M is a 32-bit processor that is optimized for
high performance DSP applications. The ADSP-21160M
includes an 80 MHz core, a dual-ported on-chip SRAM, an
integrated I/O processor with multiprocessing support, and
multiple internal buses to eliminate I/O bottlenecks.
The ADSP-21160M introduces Single-Instruction,
Multiple-Data (SIMD) processing. Using two computa-
tional units (ADSP-2106x SHARC DSPs have one), the
ADSP-21160M can double performance versus the
ADSP-2106x on a range of DSP algorithms.
Fabricated in a state of the art, high speed, low power
CMOS process, the ADSP-21160M has a 12.5 ns instruc-
tion cycle time. With its SIMD computational hardware
running at 80 MHz, the ADSP-21160M can perform 480
million math operations per second.
Table 1 shows performance benchmarks for the
ADSP-21160M.
These benchmarks provide single-channel extrapolations of
measured dual-channel processing performance. For more
information on benchmarking and optimizing DSP code for
single- and dual-channel processing, see Analog Devices’s
website.
The ADSP-21160M continues SHARC’s industry-leading
standards of integration for DSPs, combining a
high-performance 32-bit DSP core with integrated, on-chip
system features. These features include a 4M bit dual
ported SRAM memory, host processor interface, I/O
processor that supports 14 DMA channels, two serial ports,
six link ports, external parallel bus, and glueless
multiprocessing.
