SIMULATORS

There is a simulator for each ADSP-2100 Family processor that

provides instruction-level simulation of program execution. The

Simulator models system memory and I/O according to the

contents of the system architecture file, and provides windows

to display different portions of the target system hardware. The

Graphical User Interface (GUI) lets system designers inter-

actively observe and alter register and memory contents,

providing a powerful debug environment. Simulator commands

can be entered from the mouse or keyboard.

Features offered by the ADSP-2100 Family Simulators include

the following:

• Program and Data Memory Simulation

• Memory-Mapped I/O Port Simulation

• Interrupt Simulation

• Program Booting (from PROM or host processor) Simulation

• Code Execution Pattern Profiling for Program Optimization

• On-Line Help

• Reconfigurable Windows

• Same User Interface as EZ-ICE Emulators

CBUG C SOURCE-LEVEL DEBUGGER

The Simulators are seamlessly integrated with the CBUG C

source-level debugger. CBUG supports the following

operations:

• Run, Step, Next, and Finish Program Execution Commands

• C Source Code Breakpoints

• Local and Global Variable Display with Auto Refresh

Examines Value of Variables at Previously Executed

Instructions

• Symbol Look-Up

HARDWARE TOOLS

EZ-KIT Lite

The ADSP-21xx EZ-KIT Lite is a low-cost, easy to use

development platform on which you can quickly get started with

your ADSP-2100 Family based DSP software design. The EZ-

KIT Lite is a complete development system package that

includes:

• ADDS-2181 EZ-LAB Board

• MS-Windows 3.1 Based Monitor Software

• Development Software Kit (upgradable to complete ADSP-

2100 Family Development Software package for full-featured

development of final systems)

• Demo Programs

- Digital Filtering

- Speech Compression

- FFT

- Echo Cancellation

- DTMF Tone Generation

- MPEG Audio Playback

The EZ-Kit Lite uses the ADDS-2181 EZ-LAB as a

development platform on which you can develop software

applications for any of the ADSP-2100 Family DSPs. This is

possible because the ADSP-2181 represents a superset of the

features of the ADSP-2101/2105/2111/2115/2171 processors.

With the ADSP-2181’s 32K words of on-chip RAM, there is no

need for additional RAM devices on the EZ-LAB board. The

board simply requires connection to power, an analog input

source, and amplified speakers to be able to run audio

applications and demos.

The EZ-LAB board can run in a stand-alone mode, or it can be

connected to the RS-232 port of your PC. A Windows-based

monitor program lets you interactively download programs and

interrogate the ADSP-2181 (see Figure 1). The board comes

with a socketed EPROM so that you can run the monitor

program or demonstrations provided—or you can plug in an

EPROM containing your own code.
