ADSP-21469: High Performance Fourth Generation DSP

The ADSP-21467/ADSP-21469 SHARC® processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processors are source code compatible with the ADSP-2126x, ADSP-2136x, ADSP-2137x, and ADSP-2116x DSPs, as well as with first generation ADSP-2106x SHARC processors in SISD (singleinstruction, single-data) mode. These 32-bit/40-bit floatingpoint processors are optimized for high performance audio applications with their large on-chip SRAM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications/peripheral interfaces (DAI/DPI).

ADSP-21467/ADSP-21469主要特性:

High performance 32-bit/40-bit floating-point processor optimized for high performance audio processing

Single-instruction, multiple-data (SIMD) computational architecture

5 Mbits of on-chip RAM, 4 Mbits of on-chip ROM

Up to 450 MHz operating frequency

Qualified for automotive applications,

Code compatible with all other members of the SHARC family

Available with unique audiocentric peripherals such as the digital applications interface, DTCP (digital transmission content protection protocol), serial ports, precision clock generators, S/PDIF transceiver, asynchronous sample rate converters, input data port, and more

ADSP-21469 EZ-BoardTM Evaluation System

SHARC processors are based on a 32-bit super Harvard architecture that includes a unique memory architecture comprised of two large on-chip, dual-ported SRAM blocks coupled with a sophisticated IO processor, which gives a SHARC processor the bandwidth for sustained high-speed computations. SHARC processors represents today’s de facto standard for floating-point processing, targeted toward premium audio applications.

The ADSP-21469 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-2146x SHARC® Processors via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-21469 hardware and software development, and quickly prototype a wide range of applications.

The EZ-KIT Lite includes an ADSP-21469 SHARC Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment, including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only.

The evaluation board is designed to be used in conjunction with the VisualDSP++® development environment to test the capabilities of the ADSP-21469 SHARC processors. The VisualDSP++ development environment aids advanced application code development and debug, such as:

• Create, compile, assemble, and link application programs written in C++, C, and ADSP-21469 assembly

• Load, run, step, halt, and set breakpoints in application programs

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Access to the ADSP-21469 processor from a personal computer (PC) is achieved through a USB port or an external JTAG emulator. The USB interface of the standalone debug agent gives unrestricted access to the ADSP-21469 processor and evaluation board’s peripherals. Analog Devices JTAG emulators offer faster communication between the host PC and target hardware.
