| The design of a signal processing system can involve
many iterations. An algorithm is developed, which must then be coded and
experimentally tested. The results of this testing are then used to
refine the algorithm which typically requires more coding, and the process is
repeated. This method of design can result in many hours of tedious
code-writing, greatly lengthening the process. By automating the
software-coding process and integrating experimental testing, control system
designs can be completed in a fraction of the time traditionally
required.
Traditional Design Process Making use of the automated code generation capabilities of
MATLAB®'s Real-Time Workshop® package, SDL has designed interfaces for a number of DSP chips,
including the TI C31, C44, and C6x processor families and Analog Devices
SHARC® processor families. This allows algorithms to be
designed as Simulink® block diagrams, and then be built into
fully-commented DSP code with a single mouse click. Code is automatically
compiled, optimized, linked, and downloaded to the target processor.

To facilitate experimental testing and verification of the algorithm, an "external-mode" interface to Simulink is also designed. This allows the user to log data from the model, as well as to modify critical parameter values on the fly, while using Simulink as a graphical front-end to the real-time execution. A method of modifying parameters and logging data for pre-built models, separate from the MATLAB / Simulink software package, is currently in development. SDL is actively developing support for additional processor families.
