GENERAL DESCRIPTION
The ADSP-21061 SHARC—Super Harvard Architecture Com-
puter—is a signal processing microcomputer that offers new
capabilities and levels of performance. The ADSP-21061
SHARC is a 32-bit processor optimized for high performance
DSP applications. The ADSP-21061 builds on the ADSP-21000
DSP core to form a complete system-on-a-chip, adding a dual-
ported on-chip SRAM and integrated I/O peripherals supported
by a dedicated I/O bus.
Fabricated in a high speed, low power CMOS process, the
ADSP-21061 has a 20 ns instruction cycle time and operates at
50 MIPS. With its on-chip instruction cache, the processor can
execute every instruction in a single cycle. Table 1 shows perfor-
mance benchmarks for the ADSP-21061/ADSP-21061L.
The ADSP-21061 SHARC represents a new standard of integra-
tion for signal computers, combining a high performance
floating-point DSP core with integrated, on-chip system fea-
tures including 1M bit SRAM memory, a host processor
interface, a DMA controller, serial ports, and parallel bus con-
nectivity for glueless DSP multiprocessing.
The ADSP-21061 continues SHARC’s industry-leading stan-
dards of integration for DSPs, combining a high performance
32-bit DSP core with integrated, on-chip system features.
The block diagram on Page 1, illustrates the following architec-
tural features:
Computation units (ALU, multiplier, and shifter) with a
shared data register file
Data address generators (DAG1, DAG2)
Program sequencer with instruction cache
PM and DM buses capable of supporting four 32-bit data
transfers between memory and the core at every core pro-
cessor cycle
Interval timer
On-chip SRAM
External port for interfacing to off-chip memory and
peripherals
Host port and multiprocessor interface
DMA controller
Serial ports
JTAG test access port
SHARC FAMILY CORE ARCHITECTURE
The ADSP-21061 includes the following architectural features
of the ADSP-21000 family core. The ADSP-21061 processors
are code- and function-compatible with the ADSP-21020,
ADSP-21060, and ADSP-21062 SHARC processors.
Independent, Parallel Computation Units
The arithmetic/logic unit (ALU), multiplier, and shifter all per-
form single-cycle instructions. The three units are arranged in
parallel, maximizing computational throughput. Single multi-
function instructions execute parallel ALU and multiplier oper-
ations. These computation units support IEEE 32-bit single-
precision floating-point, extended-precision 40-bit floating-
point, and 32-bit fixed-point data formats.
Data Register File
A general-purpose data register file is used for transferring data
between the computation units and the data buses, and for stor-
ing intermediate results. This 10-port, 32-register (16 primary,
16 secondary) register file, combined with the ADSP-21000
Harvard architecture, allows unconstrained data flow between
computation units and internal memory.
