Introduced here are how Core Independent Peripherals can reduce processor resources requirements and allow for the implementation of parallel processes. The CIPs allow PIC MCUs to perform extremely complex and dedicated tasks with little to no interaction with the CPU, leading to enhanced performance. For example, the crypto engine is capable of supporting AES, DES and 3DES symmetric encryption and decryption. In order to implement these routines in software, it requires about 1 to 6 KB of Flash and 100 to 400 Bytes of RAM. With the use of the crypto engine CIP, there is almost no Flash or RAM requirement and these resources are available to perform other parallel functions of the end application. The crypto engine, being a hardware module, has 10 times higher throughput compared to similar implementation in software, boosting the performance significantly.
