Product Release Description

Product Release Description

VisualDSP++ is the Analog Devices project management and development
environment for signal processing (DSP) applications. VisualDSP++ 4.5
integrates a graphical user interface and code generation and debugging
tools, enabling programmers to move easily between editing, building,
debugging, and deployment of final products.

The VisualDSP++ 4.5 CD-ROM supplies the code generation tool chain
comprised of the processor-specific software necessary for completing a
DSP-based project: simulator, assembler, C/C++ compiler and libraries,
linker, loader, splitter, and utilities. Analog Devices also provides
VisualDSP++ Kernel (VDK).

The product CD-ROM also includes an evaluation suite of the EZ-KIT
Lite software, which provides an easy method for initial evaluation of a
target processor system and allows application prototyping.

The successor to VisualDSP++ 4.0, VisualDSP++ 4.5 incorporates a
number of new features and enhancements, as described in Chapter 2,

“VisualDSP++ 4.5 New Features and Enhancements”.
