SHARC
Digital Signal Processor
ADSP-21160M/ADSP-21160N
SUMMARY
FEATURES
High performance 32-bit DSP—applications in audio, medical, military, graphics, imaging, and communication
Super Harvard architecture—4 independent buses for dual
data fetch, instruction fetch, and nonintrusive, zero-overhead I/O
Backward compatible—assembly source level compatible
with code for ADSP-2106x DSPs
Single-instruction, multiple-data (SIMD) computational
architecture—two 32-bit IEEE floating-point computation
units, each with a multiplier, ALU, shifter, and register file
Integrated peripherals—integrated I/O processor, 4M bits
on-chip dual-ported SRAM, glueless multiprocessing features, and ports (serial, link, external bus, and JTAG)
100 MHz (10 ns) core instruction rate (ADSP-21160N)
Single-cycle instruction execution, including SIMD operations in both computational units
Dual data address generators (DAGs) with modulo and bitreverse addressing
Zero-overhead looping and single-cycle loop setup, providing efficient program sequencing
IEEE 1149.1 JTAG standard Test Access Port and on-chip
emulation
400-ball 27 mm × 27 mm PBGA package
Available in lead-free (RoHS compliant) package
200 million fixed-point MACs sustained performance
(ADSP-21160N)
