detection. Permanent damage may occur on devices

subjected to high-energy discharges. Proper ESD

precautions are recommended to avoid performance

degradation or loss of functionality. Store unused

EZ-KIT Lite boards in the protective shipping

package.

PREFACE

Thank you for purchasing the ADSP-21262 EZ-KIT Lite®, Analog

Devices (ADI) evaluation system for SHARC®processors.

The 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 pro-

cessor, which gives SHARC the bandwidth for sustained high-speed

computations. SHARC represents today’s de facto standard for float-

ing-point DSP targeted for premium audio applications.

The evaluation system is designed to be used in conjunction with the

VisualDSP++®development environment to test the capabilities of the

ADSP-21262 SHARC processors. The VisualDSP++ development envi-

ronment gives you the ability to perform advanced application code

development and debug, such as:

• Create, compile, assemble, and link application programs written

in C++, C, and ADSP-21262 assembly

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

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Access to the ADSP-21262 processor from a personal computer (PC) is

achieved through a USB port or an optional JTAG emulator. The USB

interface gives unrestricted access to the ADSP-21262 processor and the

xii ADSP-21262 EZ-KIT Lite Evaluation System Manual

evaluation board peripherals. Analog Devices JTAG emulators offer faster

communication between the host PC and target hardware. Analog Devices

carries a wide range of in-circuit emulation products. To learn more about

Analog Devices emulators and DSP development tools, go to

http://www.analog.com/dsp/tools/.

ADSP-21262 EZ-KIT Lite provides example programs to demonstrate the

capabilities of the evaluation board.

LThe VisualDSP++ license provided with this EZ-KIT Lite evalua-

tion system limits the size of a user program’s code to 10922 words

of program memory.

The board features:

• Analog Devices ADSP-21262 processor

D136-pin BGA package

D300 MHz Core Clock Speed

• Synchronous Read Access Memory (SRAM)

D512 Kbit x 8-bit

• Flash Memory

The EZ-KIT Lite board has a total of 1 MB of parallel Flash memory and

512 Kbit of SPI Flash memory. The Flash memories can store user-spe-

cific boot code, allowing the board to run as a stand-alone unit. For more

information, see “Using External Memory” on page 2-2 and “Boot Mode

and Clock Ratio Select Switch (SW10)” on page 3-11. The board also has

512 KB of SRAM, which can be used at runtime.

The DAI of the DSP connects to the AD1835A audio codec and the

CS8416 SPDIF receiver. These devices allow you to create digital and ana-

log audio signal processing applications. See “Using Analog Audio” on

page 2-3 and “Using Digital Audio” on page 2-5 for more information.

Purpose of This Manual

xiv ADSP-21262 EZ-KIT Lite Evaluation System Manual

Additionally, the EZ-KIT Lite board provides access to all of the proces-

sor’s peripheral ports. Access is provided in the form of a three-connector

expansion interface. See “Expansion Interface” on page 3-7 for details.

Purpose of This Manual

The ADSP-21262 EZ-KIT Lite Evaluation System Manual provides

instructions for using the hardware and installing the software on your

PC. The text includes guidelines for running your own code on the

ADSP-21262 EZ-KIT Lite. The manual also describes the board’s config-

uration and components. Finally, a schematic and a bill of materials are

provided as a reference for future ADSP-21262 board designs.

Intended Audience

This manual is a user’s guide and reference to the ADSP-21262 EZ-KIT

Lite evaluation system. Programmers who are familiar with the Analog

Devices SHARC processor architecture, operation, and programming are

the primary audience for this manual.

Programmers who are unfamiliar with Analog Devices SHARC processors

can use this manual in conjunction with the ADSP-2126x SHARC Core

Reference and ADSP-21262/21266 Peripherals Manual and the

ADSP-21160 SHARC DSP Instruction Set Reference, which describe the

DSP’a architecture and instruction set. Programmers who are unfamiliar

with VisualDSP++ should refer to the VisualDSP++ online Help and the

VisualDSP++ user’s or getting started guides. For the locations of these

documents, see “Related Documents” on page -xviii.
