GENERAL DESCRIPTION
The ADSP-2106x SHARC—Super Harvard Architecture Com-
puter—is a 32-bit signal processing microcomputer that offers
high levels of DSP performance. The ADSP-2106x 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 periph-
erals supported by a dedicated I/O bus.
Fabricated in a high speed, low power CMOS process, the
ADSP-2106x has a 25 ns instruction cycle time and operates at
40 MIPS. With its on-chip instruction cache, the processor can
execute every instruction in a single cycle. Table 2 shows perfor-
mance benchmarks for the ADSP-2106x.
The ADSP-2106x 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 up to 4M bit SRAM memory (see Table 1), a
host processor interface, DMA controller, serial ports and link
port, and parallel bus connectivity for glueless DSP
multiprocessing.
The ADSP-2106x 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 and link ports
JTAG Test Access Port
SHARC FAMILY CORE ARCHITECTURE
The ADSP-2106x includes the following architectural features
of the ADSP-21000 family core. The ADSP-2106x processors
are code- and function-compatible with the ADSP-21020.
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.
