GENERAL NOTE
This data sheet represents production released specifications
for the ADSP-21061 5 V and ADSP-21061L 3.3 V proces-
sors. ADSP-21061 is used throughout this data sheet to refer to
both devices unless expressly noted.
GENERAL DESCRIPTION
The ADSP-21061 is a member of the powerful SHARC family
of floating point processors. The SHARC—Super Harvard
Architecture Computer—are signal processing microcomputers
that offer new capabilities and levels of integration and perfor-
mance. The ADSP-21061 is a 32-bit processor optimized for
high performance DSP applications. The ADSP-21061 com-
bines the ADSP-21000 DSP core with a dual-ported on-chip
SRAM and an I/O processor with a dedicated I/O bus to form a
complete system-in-a-chip.
Fabricated in a high-speed, low-power CMOS process, the
ADSP-21061 has a 20 ns instruction cycle time operating at up
to 50 MIPS. With its on-chip instruction cache, the processor can
execute every instruction in a single cycle. Table I shows perfor-
mance benchmarks for the ADSP-21061/ADSP-21061L.
The ADSP-21061 SHARC
combines a high-performance float-
ing-point DSP core with integrated, on-chip system features,
including a 1 Mbit SRAM memory, host processor interface,
DMA controller, serial ports and parallel bus connectivity for
glueless DSP multiprocessing.
