PREFACE

Thank you for purchasing the ADSP-BF548 EZ-KIT Lite®, Analog Devices, Inc. evaluation system for ADSP-BF548 Blackfin® processors.

Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing (DSP) characteristics towards delivering signal processing performance in a microprocessor-like environment.

The evaluation board is designed to be used in conjunction with the VisualDSP++® development environment to test the capabilities of ADSP-BF548 Blackfin processors. The VisualDSP++ development environment 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-BF548 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-BF548 processor from a personal computer (PC) is achieved through a USB port or an optional JTAG emulator. The USB interface provides unrestricted access to the ADSP-BF548 processor and the evaluation board peripherals. Analog Devices JTAG emulators offer

• “Installing VisualDSP++ and the EZ-KIT Lite” on page 1-2

• “Starting VisualDSP++ and Connecting to the EZ-KIT Lite” on

page 1-3

• “Example 1: Building and Running an Application” on page 1-6

• “Example 1: Sorts.c File” on page 1-9

Getting Started with ADSP-BF548 EZ-KIT Lite 1-1

Installing VisualDSP++ and the EZ-KIT Lite

If you have not already done so, install the ADSP-BF548 EZ-KIT Lite. Ensure the board is disconnected from your PC, then install VisualDSP++ by following instructions in the VisualDSP++ Installation Quick Reference Card, steps 1 to 3.

Once the installation is complete, the amber LED (labeled MON, found near the USB jack) is illuminated, indicating a successful physical connection between the PC and EZ-KIT Lite.

Install your license following instructions in the VisualDSP++ Installation Quick Reference Card, step 4.

There are two USB interfaces on the ADSP-BF548 EZ-KIT Lite. Be sure to use the debugger’s interface (labelled USB Debug Agent) when connecting your computer to the board with provided USB cable. The other USB interface (labelled USB-OTG) is for applications use.

1-2 Getting Started with ADSP-BF548 EZ-KIT Lite

Programming ADSP-BF548 EZ-KIT Lite with VisualDSP++

Starting VisualDSP++ and Connecting to the EZ-KIT Lite

If you have not already done so, start VisualDSP++. Use the Windows Start menu to launch the VisualDSP++ environment (also called the Integrated Development and Debugging Environment or IDDE).

When VisualDSP++ first launches, it is disconnected from your EZ-KIT Lite or any other kind of debugging session (Figure 1-1).

Figure 1-1. VisualDSP++ Main Window

A VisualDSP++ debugging session consists of a session type and target processor. There are three basic session types:

Getting Started with ADSP-BF548 EZ-KIT Lite 1-3

Starting VisualDSP++ and Connecting to the EZ-KIT Lite

• EZ-KIT Lite. This is the dedicated USB connection between the

PC and EZ-KIT Lite. The connection is simple to manage and is an integral part of the EZ-KIT Lite. However, the connection is available with the EZ-KIT Lite only. Once your custom hardware board is available for development, you will use an emulator session (description follows) to connect to the custom hardware.

• Simulator. This is a software model of the processor. Simulators

offer unique advantages, the first being that no external hardware is required, a great benefit when using VisualDSP++ on the road. Furthermore, simulators offer a deep insight to the internal workings of the processor (pipelines, caches, and more), which is not possible with hardware-based sessions. The downside is that a simulator is several orders of magnitude slower than actual hardware. The software model simulates only the processor, making it difficult to accurately simulate a complex system that involves more than the processor.

VisualDSP++ includes two types of Blackfin simulators: a cycle-accurate, interpreted simulator and a functional, compiled simulator. A cycle-accurate simulator is a completely accurate model of the Blackfin processor and allows you to fully visualize the inner-workings of the processor. The compiled simulator sacrifices the detailed view but allows you to simulate much more quickly, at millions of simulated cycles per second depending on the speed of your PC.

• Emulator. This is a JTAG emulator, the ideal device for connect-

ing to hardware, giving the best performance and maximum flexibility. An emulator is a separate module that provides a

1-4 Getting Started with ADSP-BF548 EZ-KIT Lite

Programming ADSP-BF548 EZ-KIT Lite with VisualDSP++

high-bandwidth USB or PCI connection between the PC and the target device. An emulator is required to connect to a non-EZ-KIT Lite target.

To inform VisualDSP++ that your target is an ADSP-BF548 processor on an EZ-KIT Lite, you must create and activate a new session. Follow these steps:

1. From VisualDSP++ Session menu, select New Session, which launches the Session Wizard (Figure 1-2).

Figure 1-2. Session Wizard

2. On the Select Processor page, ensure that Processor family is set to

Blackfin. In Choose a target processor, select ADSP-BF548. Click Next.

Getting Started with ADSP-BF548 EZ-KIT Lite 1-5

Example 1: Building and Running an Application

3. On the Select Connection Type page, select EZ-KIT Lite. Click Next.

4. On the Select Platform page, ensure that the selected platform is ADSP-BF548 EZ-KIT Lite via Debug Agent. Specify your own Session name for your session or accept the default name. Click Next.

5. On the Finish page, check the presented information and click Finish. VisualDSP++ creates the new session and connects to the

ADSP-BF548 EZ-KIT Lite. Once connected, the main window’s title is changed to include the session name set in step 4.

Creating a particular session is a one-time job. VisualDSP++ records a session’s details between runs and, by default, tries to reconnect to the session that was in force when VisualDSP++ last ran. You can create more than one session, possibly changing the connection type to Simulator or Emulator. The Session menu allows you to swap between sessions as you wish.

Examples in this manual assume that you are using an ADSP-BF548 EZ-KIT Lite session.

Example 1: Building and Running an Application

Now it is time to start our first C program. “Example 1: Sorts.c File” on

page 1-9 is the C program we start in this chapter and develop in the fol-

lowing one. The program randomizes and sorts two arrays using classic sorting algorithms: the bubble sort and the quick sort. If you are familiar with the algorithms, you know that the quick sort, true to its name, is the faster of the two algorithms (on average,
