EVM21061 Software Support

The EVM21061 is fully supported by Signalogic's Hypersignal®-Macro and Hypersignal-Acoustic software packages. In addition, both the board and Hypersignal packages can also be used with DirectDSP, which offers C/C++, Visual Basic, and MATLAB®programming interfaces. Used in conjunction with the EVM21061, the DirectDSP/Hypersignal software combination provides sophisticated DSP-based instrumentation, visualization and display of waveforms, block-diagram based automationof development and test sequences, and numerous tools for all levels of DSP product, system, and algorithm development. The complete range of DSP/mathfunctions, interactive waveform display and editing, difference equations, filter design, and real-time code development facilities offered by thesoftware is fully active with the EVM21061. Display examples include interactive frequency domain waterfall and contour (joint time-frequency), .WAV display, pole-zero, unwrapped phase, and group delay.

Signalogic software takes full advantage of the multichannel capability of the EVM21061. Instruments can show any two of the four channels at once, and any number and combination of the four channels can be recorded and generated continuously to/from hard disk. Instrumentation includes digitaloscilloscope, real-time spectrum analyzer, continuous signal generator (up to 4 channels), stimulus & response measurement, digital tape recorder, and more. The spectrum analyzer allows measurements such as transfer function (deconvolution), impulse response, and selective-band real-time digital filtering to be performed.

Additionally, the TMS320C6x DSP Source Code Interface allows real-time code to be designed, simulated and developed for the 2106x, and results downloaded, tested and graphically debugged in real-time with the Hypersignal and DirectDSP packages.
