1 FEATURES AND TOOLS

This chapter contains the following topics.

• “VisualDSP++ Features” on page 1-1

• “New Features in Release 4.0” on page 1-5

• “Code Development Tools” on page 1-6

VisualDSP++ Features

VisualDSP++ provides these features:

• Extensive editing capabilities. Create and modify source files by using multiple language syntax highlighting, drag-and-drop, bookmarks, and other standard editing operations. View files generated by the code development tools.

• Flexible project management. Specify a project definition that identifies the files, dependencies, and tools that you use to build projects. Create this project definition once or modify it to meet changing development needs.

VisualDSP++ 4.0 Getting Started Guide 1-1

VisualDSP++ Features

• Easy access to code development tools. Analog Devices provides these code development tools: C/C++ compiler, assembler, linker, splitter, and loader. Specify options for these tools by using dialog boxes instead of complicated command-line scripts. Options that control how the tools process inputs and generate outputs have a one-to-one correspondence to command-line switches. Define options for a single file or for an entire project. Define these options once or modify them as necessary.

• Flexible project build options. Control builds at the file or project level. VisualDSP++ enables you to build files or projects selectively, update project dependencies, or incrementally build only the files that have changed since the previous build. View the status of your project build in progress. If the build reports an error, double-click on the file name in the error message to open that source file. Then correct the error, rebuild the file or project, and start a debug session.

• VisualDSP++ Kernel (VDK) support. Add VDK support to a project to structure and scale application development. The Kernel page of the Project window enables you to manipulate events, event bits, priorities, semaphores, and thread types.

• Flexible workspace management. Create up to ten workspaces and quickly switch between them. Assigning a different project to each workspace enables you to build and debug multiple projects in a single session.

• Easy movement between debug and build activities. Start the debug session and move freely between editing, build, and debug activities.

VisualDSP++ 4.0 Getting Started Guide 1-3

VisualDSP++ Features

VisualDSP++ reduces debugging time by providing these key features:

• Easy-to-use debugging activities. Debug with one common, easy-to-use interface for all processor simulators and emulators, or hardware evaluation and development boards. Switch easily between these targets.

• Multiple language support. Debug programs written in C, C++, or assembly, and view your program in machine code. For programs written in C/C++, you can view the source in C/C++ or mixed C/C++ and assembly, and display the values of local variables or evaluate expressions (global and local) based on the current context.

• Effective debug control. Set breakpoints on symbols and addresses and then step through the program’s execution to find problems in coding logic. Set watchpoints (conditional breakpoints) on registers, stacks, and memory locations to identify when they are accessed.

• Tools for improving performance. Use the trace, profile, and linear and statistical profiles to identify bottlenecks in your DSP application and to identify program optimization needs. Use plotting to view data arrays graphically. Generate interrupts, outputs, and inputs to simulate real-world application conditions.

1-4 VisualDSP++ 4.0 Getting Started Guide

New Features in Release 4.0

Release 4.0 includes these new features and enhancements:

• Support for new processors. VisualDSP++ supports these new Blackfin processors: ADSP-BF534, ADSP-BF536, ADSP-BF537, ADSP-BF538 ADSP-BF539, ADSP-BF566

• New Project Wizard. This feature lets you create and configure a DSP project with code that sets up peripherals like cache, DMA ports, I/O ports, and so on. An LDF can be added to the project to link in only necessary libraries, and plug-ins can be added to analyze system performance and determine optimal parameters for the peripherals. Selecting New and then Project from the File menu now launches a New Project Wizard where you specify project options such as Name, Directory, Project type (standard application or multithreaded application using VDK), Processor, Silicon revision, Output type (executable file or Loader file).

Features and Tools

• Build engine enhancements. You can select multiple files in the Project window and issue a Build Files command to build multiple

files simultaneously. You can use a Batch Build command to open a dialog box that lets you manage batch builds for multiple build targets. In the Output window, you now have the option of displaying only file names instead of command lines while building a project. A new Project Group file lets you store project group information in a file to allow the quick restoring and convenient sharing of information. The Project menu includes new project group options (Open Project Group, Save Project Group, Save Project Group As, and Close Project Group).

VisualDSP++ 4.0 Getting Started Guide 1-5

New Features in Release 4.0

• Changes to Image Viewer. In addition to Grayscale 8 and RGB24, these pixel formats are now supported: Grayscale 12, Grayscale 16, RGB555, RGB565, and RGB32. These YUV pixel formats are also supported: YUV2 (4:2:2), YVYU (4:2:2), UYVY (4:2:2), and IYU2 (4:4:4). Display and processing speed has been improved through the use of the graphics device interface (GDI+). Image Viewer can now convert color formats from YUV to RGB and visa-versa, and transfer JPEG binary data to and from DSP memory. New functions have been added for advanced image processing (rotating and flipping images, filtering, auto-refreshing). New controls have been added to the Image Configuration dialog box, a toolbar has been added to the Image Viewer window.

• New Project Options dialog box. A tree navigation control on the left side of the dialog box has replaced tabs for selecting the page view (General, Compiler, Assemble, Link, Load, Pre-build, or Post-build). Other changes include new fields and pages for configuring project options.

• Changes to licensing management. Three types of licenses are available: TST (evaluation), KIT (evaluation), and ADI (permanent).

A TST (test drive) license provides unlimited (unrestricted) access to VisualDSP++ for emulation and simulation. You must register the software to receive a TST serial number, which expires 90 days after installation. After the 90 days, the software is inoperable.

A KIT license provides 10 days to register and validate the installation. Once validated, the KIT licence extends to 90 (ninety) days of a full evaluation in total. At the end of the evaluation period,

unless you have added a permanent license, simulator and emulator connections become prohibited and the size of the user program is

limited.

1-6 VisualDSP++ 4.0 Getting Started Guide

An ADI license provides 30 (thirty) days to register and validate the installation for a permanent use. If you fail to register and validate your installation during the 30-day evaluation period, your copy of VisualDSP++ 4.0 becomes inoperable.

Code Development Tools

Code development tools include:

• C/C++ compiler

• Run-time library with over 100 math, DSP, and C run-time library routines

•Assembler

•Linker

Features and Tools

• Splitter

•Loader

• Simulator

• Emulator (must be purchased separately from VisualDSP++)

These tools enable you to develop applications that take full advantage of your processor’s architecture.

The VisualDSP++ linker supports multiprocessing, shared memory, and memory overlays.

VisualDSP++ 4.0 Getting Started Guide 1-7

Code Development Tools

The code development tools provide these key features:

• Easy-to-program C, C++, and assembly languages. Program in C/C++, assembly, or a mix of C/C++ and assembly in one source. The assembly language is based on an algebraic syntax that is easy to learn, program, and debug.

• Flexible system definition. Define multiple types of executables for a single type of processor in one Linker Description File ( Specify input files, including objects, libraries, shared memory files, overlay files, and executables.

• Support for overlays, multiprocessors, and shared memory executables. The linker places code and resolves symbols in multiprocessor memory space for use by multiprocessor systems. The loader enables you to configure multiple processors with less code and faster boot time. Create host, link port, and PROM boot images.

2 BASIC TUTORIAL

This chapter contains the following topics.

• “Overview” on page 2-1

• “Exercise One: Building and Running a C Program” on page 2-3

• “Exercise Two: Modifying a C Program to Call an Assembly Rou-

tine” on page 2-16

• “Exercise Three: Plotting Data” on page 2-37

• “Exercise Four: Linear Profiling” on page 2-51

Overview

The Basic Tutorial demonstrates key features and capabilities of the VisualDSP++ Integrated Development and Debugging Environment (IDDE). The exercises use sample programs written in C and assembly for Blackfin processors.

You can use different Blackfin processors with only minor changes to the Linker Description Files (.LDFs) included with each project. VisualDSP++ includes basic Linker Description Files for each processor type in the folder. For Blackfin processors, the folder’s default installation path is:

Program Files\Analog Devices\VisualDSP 4.0\Blackfin\ldf

The source files for these exercises are installed during the VisualDSP++ software installation.

VisualDSP++ 4.0 Getting Started Guide 2-1

ldf

Overview

The tutorial contains four exercises:

•In Exercise One, you start up VisualDSP++, build a project containing C source code, and profile the performance of a C function.

•In Exercise Two, you create a new project, create a Linker Description File to link with the assembly routine, rebuild the project, and profile the performance of the assembly language routine.

•In Exercise Three, you plot the various waveforms produced by a Finite Impulse Response (FIR) algorithm.

•In Exercise Four, you use linear profiling to examine the efficiency of the FIR algorithm used in Exercise Three. Using the collected linear profile data, you pinpoint the most time-consuming areas of the algorithm, which are likely to require hand tuning in the assembly language.

The ADSP-BF53x Family Simulator and ADSP-BF533 processor are used for all exercises.

Tip: Become familiar with the VisualDSP++ toolbar buttons, shown in

Figure 2-1. They are shortcuts for menu commands such as Open a file

and Run a program. Toolbar buttons and menu commands that are not available for tasks are disabled and displayed in gray.
