Product details
Overview
ADSP-21062KB-160 from Analog Devices is a 40 MHz, 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, integrated DMA controller, six link ports, and IEEE JTAG 1149.1 debug interface-designed for real-time audio processing, radar signal conditioning, and industrial motor control systems.
For engineers reviewing the ADSP-21062KB-160 datasheet, ADSP-21062KB-160 pinout, ADSP-21062KB-160 application, or ADSP-21062KB-160 equivalent, key selection criteria include sustained 80 MFLOPS performance, 240 MBps interprocessor link throughput, host interface compatibility with 16-/32-bit microprocessors, and thermal-enhanced MQFP_PQ4 package suitability for convection-cooled embedded DSP modules.
Technical Context
The ADSP-21062KB-160 implements a Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand access, and nonintrusive I/O-supporting single-cycle execution of multiply-ALU-shifter operations. Its dual data address generators (DAG1/DAG2) provide hardware circular buffering and bit-reverse addressing essential for FFT and filter implementations.
It integrates a dedicated I/O processor (IOP), 10-channel DMA controller with background transfer capability, and glueless multiprocessing support via distributed bus arbitration across up to six nodes. The 2 Mbit dual-ported SRAM is split into two 1 Mbit blocks, each independently accessible by core and DMA in one cycle-enabling concurrent code execution and data streaming without contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Clock Rate | 40 MHz - enables 25 ns instruction cycle time and full-speed execution of all instructions including multiply-accumulate and FFT butterfly operations. |
| Floating-Point Performance | 120 MFLOPS peak / 80 MFLOPS sustained - delivers deterministic real-time computation for multi-channel audio codecs or beamforming algorithms. |
| On-Chip Memory | 2 Mbit dual-ported SRAM - organized as two 1 Mbit blocks supporting concurrent core + DMA access without wait states. |
| Link Port Throughput | 240 MBps aggregate - six 4-bit link ports clocked at 2× core rate enable high-bandwidth point-to-point inter-DSP communication. |
| DMA Channels | 10 channels - includes 4 external port, 4 serial port, and 2 link port dedicated paths for zero-overhead data movement during full-speed core operation. |
| Host Interface | 16-/32-bit asynchronous bus - memory-mapped access allows host processors to read/write internal memory and IOP registers without core intervention. |
| JTAG Support | IEEE 1149.1 compliant - enables in-circuit emulation, boundary scan testing, and real-time debugging via standard TAP controller. |
