In today’s world the audio and video is completely digitized. Once audio signal is out of microphone or any such audio source the analog is sampled, coded, modulated, compressed and processed into digital format of one (1) zero (0) world. It’s called Digital Signal Processing. The reproduction of this digital signal into audio is also done by the same DSP. The traditional X86 architecture called Van Neumann is not a right fit for handling various algorithms to process this kind of digital data. The popular architecture to handle complex digital signal processing algorithms is called Harvard Architecture, used in the very popular Advanced Risc Machine Processors. Here below we have compared the differences between these two architectures.
