The high performance, low cost and re-programmability of today's Digital Signal Processors (DSPs) provide an ideal hardware platform for control, communication and signal processing applications. When combined with rapid prototyping software, engineers can design DSP-based applications much faster and with less cost than traditional methods. Major companies like HR Textron, GEC-Marconi and LMT (an SKF Group Company) are successfully using VisSim/DSP solutions to get their mission critical applications to market faster.

The choice of the right rapid prototyping software is a critical product design decision. The primary requirements of a productive rapid prototyping software package include:

• Ease-of-use
• Quality and efficiency of C code (e.g., reliability, small footprint)
• Level of automation (automatic C code generation, program ming of I/O, compilation & download)
• Integration (e.g., is it truly seamless? does it offer interactive GUI & tools while the algorithm executes on the DSP?)
• Support of the software for your target DSP

VisSim/DSP is a completely integrated, native Windows program for the rapid prototyping of control, communication or signal processing applications targeted for DSPs and embedded systems. VisSim/DSP includes integrated modules for system modeling and simulation, automatic C code generation, automatic compiling-linking-downloading and real-time DSP validation and optimization. Importantly, all of these rapid prototyping tasks can be completed without writing a line of code.

An important requirement of a typical embedded system is to communicate with external systems (e.g., hardware prototypes - motors, modems or speakers) through analog and digital I/O. When an engineer elects to generate code, VisSim/DSP automatically generates and downloads target-specific code for all the I/O points included in the system. This unique capability frees the engineer from the burden of I/O programming and allows complete concentration on the design task.

"I consider VisSim/DSP to be the easiest, fastest method available for designing and implementing embedded DSP controls. It’s a well integrated and automated solution that frees the designer from having to deal with any programming at all - thus allowing me complete concentration on the design issues."
