CCS is the ti native development DSP enviroment .It is pretty sofisticated and allows plugs in to do a lot of things .like to deal with Ti's own real time OS .Also it allows to display FFt of data buffers and other formats.
But is NOT intended to help you to automaticaly produce code from a higher language description like MATLAB!
CCS allows c/c++ and assambler as input .Not matlab
But if you have proven working c,c++ or assambler algorithms .CCS has all the tools to optimize them to the target DSP ..( C2000,C5000,C6000 ,OMAP)
