Development ToolsDevelopment ToolsThe ADSP-219x is supported by VisualDSP®, an easy-to-use projectmanagement environment, comprised of an Integrated DevelopmentEnvironment (IDE) and Debugger. VisualDSP lets you manage projectsfrom start to finish from within a single, integrated interface. Because theproject development and debug environments are integrated, you canmove easily between editing, building, and debugging activities.Flexible Project Management. The IDE provides flexible project managementfor the development of DSP applications. The IDE includes accessto all the activities necessary to create and debug DSP projects. You cancreate or modify source files or view listing or map files with the IDE Editor.This powerful Editor is part of the IDE and includes multiplelanguage syntax highlighting, OLE drag and drop, bookmarks, and standardediting operations such as undo/redo, find/replace, copy/paste/cut,and go to.Also, the IDE includes access to the DSP C Compiler, C RuntimeLibrary, Assembler, Linker, Loader, Simulator, and Splitter. You specifyoptions for these Tools through Property Page dialogs. Property Page dialogsare easy to use and make configuring, changing, and managing yourprojects simple. These options control how the tools process inputs andgenerate outputs, and the options have a one-to-one correspondence tothe tools’ command line switches. You can define these options once ormodify them to meet changing development needs. You also can accessthe Tools from the operating system command line if you choose.Greatly Reduced Debugging Time. The Debugger has an easy-to-use,common interface for all processor simulators and emulators availablethrough Analog Devices and third parties or custom developments. TheDebugger has many features that greatly reduce debugging time. You canview C source interspersed with the resulting Assembly code. You can profileexecution of a range of instructions in a program; set simulatedwatchpoints on hardware and software registers, program and data mem-1-22 ADSP-219x/2191 DSP Hardware Reference
Introductionory; and trace instruction execution and memory accesses. These featuresenable you to correct coding errors, identify bottlenecks, and examineDSP performance. You can use the custom register option to select anycombination of registers to view in a single window. The Debugger canalso generate inputs, outputs, and interrupts so you can simulate realworld application conditions.Software Development Tools. Software Development Tools, which supportthe ADSP-219x family, let you develop applications that take fulladvantage of the architecture, including shared memory and memoryoverlays. Software Development Tools include C Compiler, C RuntimeLibrary, DSP and Math Libraries, Assembler, Linker, Loader, Simulator,and Splitter.C/C++ Compiler & Assembler. The C/C++ Compiler generates efficientcode that is optimized for both code density and execution time. TheC/C++ Compiler allows you to include Assembly language statementsinline. Because of this, you can program in C and still use Assembly fortime-critical loops. You can also use pretested Math, DSP, and C RuntimeLibrary routines to help shorten your time to market. The ADSP-219xfamily assembly language is based on an algebraic syntax that is easy tolearn, program, and debug.Linker & Loader. The Linker provides flexible system definition throughLinker Description Files (.LDF). In a single LDF, you can define differenttypes of executables for a single or multiprocessor system. The Linkerresolves symbols over multiple executables, maximizes memory use, andeasily shares common code among multiple processors. The Loader supportscreation of PROM, host, SPI, and UART boot images. The Loaderallows multiprocessor system configuration with smaller code and fasterboot time.3rd-Party Extensible. The VisualDSP environment enables third-partycompanies to add value using Analog Devices’ published set of ApplicationProgramming Interfaces (API).
