This paper presents the C code optimization of Oppositional Whale Grey Wolf Algorithm with Control Search Space (OWGWA-CSS) used for denoising EEG signal for its real-time implementation on floating point DSP processor TMS320C6713. In general, developers tried to speed up the program all-time which leads to increase in the code size so as increase the complexity as well as difficult readability. To make the code efficient it is important to optimize the C code. For optimizing the C code first, the MATLAB code is c…
