Joshua Adadevoh Micro Computer System 1 project Project Statement Audio data Encryption using the TI OMAP-L137 processor on the OMAP-L137 EVM. Coding is done in C utilizing lessons from the lab About the project An input audio signal is received via the codec on the board, and converted to hexadecimal values. The hex values are then passed through an encryption algorithm and are scrambled. The scrambled code is then converted back to an audio signal, and passed out through the output buffers to the codec and relayed through the speakers. Implementation I started by looking into writing my own encryption algorithm as opposed to trying one of the previous ones from old labs. I used c++ to write the algorithm on visual studios so I could test it out. My implementation was simple; I created two arrays of size 512 each to emulate the buffers pIn and pOut. I then filled the one for pIn with values from 1 to 512, and passed it through the decryption algorithm. Algorithm:
