Simulation software for Digital Signal Processing
SimDSP provides simulation of DSP algorithms written in C/C++ language by generating the necessary signals of 15-bit ADC and DAC. The programs under debugging must be written using the editor included in this software. It is not necessary to install any compiler for compiling or debugging purposes, since installers are boundle versions that includes editor, compiler and debugger. This software is available under an open source GNU license available on GitHub.
The signals that can be generated are: sinusoidal, square, triangular, data file (MatLAB format) and microphone input. Also, Gaussian additive noise (AWGN) can be included for the sine, square and triangular signals. If signals are acquired from microphone, only the following sampling frequencies are supported: 8000, 11025, 22050 and 44100Hz.
Data acquisition and processing can be performed on the sample-by-sample approach or block-oriented approach (DMA framework). For microphone mode, only block-oriented approach is available. The signals can be displayed in time or in the frequency domain.
