PREFACE

Thank you for purchasing the ADSP-21160 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-21160 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-21160 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-21160 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-21160 processor and the

viii ADSP-21160 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-21160 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 21K words of

the processor’s program memory space.

The board features:

• Analog Devices ADSP-21160 processor

• ADSP-21160M processor:

D2.5V Core Voltage

D80 MHz Core Clock Speed

• ADSP-21160N processor:

D1.9V Core Voltage

D95 MHz Core Clock Speed

• Switch-Configurable Boot Mode

• Analog Devices AD1881A 48 kHz AC’97 SoundMAX®Codec

DJumper Selectable Line-In or Mic-In 3.5 mm Stereo Jack

DLine-Out 3.5 mm Stereo Jack

• USB Debugging Interface

• SBSRAM

D512 Kb (64K x 32-bits x 2-chips)

Preface

• Flash Memory

D512 Kb (512K x 8-bits)

• Interface Connectors

D14-Pin Emulator Connector for JTAG Interface

DSPORT0 Connectors

D2 Link Port Connectors

DExpansion Interface Connectors (not populated)

• General-Purpose IO

D3 Push Buttons connected to DSP IRQs

D3 LEDs connected to DSP FLAGs

The EZ-KIT Lite board has two types of external memory: Flash memory

and SBSRAM. The Flash memory can store user-specified boot code. By

configuring the boot mode switch (SW1) and programming the Flash mem-

ory, the board can run as a stand-alone unit. For information about the

external memory, see section “Memory Map” on page 2-2.

SPORT0 is interfaced to an audio codec, facilitating audio signal processing

applications development. SPORT0 is also attached to an off-board connec-

tor for communication with other serial devices. For information about

SPORT0, see section “SPORT0 Audio Interface” on page 3-3.

Additionally, the EZ-KIT Lite board provides access to most of the pro-

cessor’s peripheral ports on populated expansion interface connectors. For

information about the expansion interface, see “External Port” on

page 3-3.

Purpose of This Manual

x ADSP-21160 EZ-KIT Lite Evaluation System Manual

Purpose of This Manual

The ADSP-21160 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-21160 EZ-KIT Lite. The manual also describes the board’s config-

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

each board modification are provided as a reference for future

ADSP-21160 board designs.

Intended Audience

This manual is a user’s guide and reference to the ADSP-21160 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-21160 SHARC Proces-

sor Hardware Reference and ADSP-21160 SHARC Processor Instruction Set

Reference, which describe the processor’s 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 -xiv.
