Accelerate a MATLAB Design with MATLAB Coder
Vision HDL Toolbox™ designs in MATLAB® must call one or more System objects for every pixel. This serial processing is efficient in hardware, but is slow in simulation. One way to accelerate simulations of these objects is to simulate using generated C code rather than the MATLAB interpreted language.
Code generation accelerates simulation by using constants for the sizes and data types of variables inside the function. This process removes the overhead of the interpreted language checking for size and data type in every line of code. You can compile a video processing algorithm and test bench into MEX functions, and use the resulting MEX file to speed up the simulation.
To generate C code, you must have a MATLAB Coder™ license.
