| VisSim/DSP - DSP & Embedded System Design 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."
