Preliminary Technical Data
DSP
Microcomputer
ADSP-21160
SUMMARY
High performance 32-bit DSP—applications in
audio, medical, military, graphics, imaging, and
communication
Super Harvard Architecture—four independent
buses for dual data fetch, instruction fetch, and
nonintrusive, zero-overhead I/O
Backwards compatible—assembly source level
compatible with code for ADSP-2106x DSPs
Single-Instruction-Multiple-Data (SIMD) com-
putational architecture—two 32-bit IEEE float-
ing-point computation units, each with a
multiplier, ALU, shifter, and register file
Integrated peripherals—integrated I/O proces-
sor, 4 Mbit on-chip dual-ported SRAM, glueless
multiprocessing features, and ports (serial, link,
external bus, & JTAG)
KEY FEATURES
80 MHz (12.5 ns) or 100 MHz (10 ns) core
instruction rate
Single-cycle instruction execution, including
SIMD operations in both computational units
600 MFLOPS peak and 400 MFLOPS sustained
performance (based on FIR)
Dual Data Address Generators (DAGs) with
modulo and bit-reverse addressing
Zero-overhead looping and single-cycle loop set-
up, providing efficient program sequencing
IEEE 1149.1 JTAG standard test access port and
on-chip emulation
400-ball 27×27mm PBGA package
