MATLAB® DSP Interface

Signalogic DSP software provides two (2) methods of interface to MATLAB:

1) Programmatical (from .m programs, usingDirectDSP® sw)

DirectDSP

Method #1 is represented by DirectDSP® software, which can be called from MATLAB programs. This Library contains a number of hardware-related functions that can be of use to MATLAB programs concerned with data acquisition or DSP. Low-level functions include onboard DSP control, download of DSP chip program files, onboard memory transfer, register and digital I/O access, sampling rate control, analog I/O parameter control, and DSP code configuration. High-level functions include waveform file acquisition, waveform file playback, continuous function generation, digital oscilloscope, spectrum analyzer, stimulus & response, and more. Over 70 types of DSP/analog hardware types can be accessed from MATLAB; click here for apartial list of supported hardware when the DirectDSP is combined withHypersignal® Macro software. Click on the following to see examples of .m programs that use the DirectDSP:

• Acquiring waveform file .m program example
• Acquiring analog input data buffers .m program example

DirectDSP is actually a standard Windows library which is intended to be called from C/C++ and Visual Basic programs, but has been modified to accept a MATLAB interface also. Thus, a proven, off-the-shelf product is available for MATLAB users--unlike the current set of .MEX and other specialized tools which work only with MATLAB, and thus cannot benefit from the full range of Windows users.
