A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs
of digital signal processing.The goal of DSPs is usually to measure, filter and/or compress continuous real-world analog signals. Most
general-purpose microprocessors can also execute digital signal processing algorithms successfully, but dedicated DSPs usually have
better power efficiency thus they are more suitable in portable devices such as mobile phones because of power consumption constraints.
DSPs often use special memory architectures that are able to fetch multiple data and/or instructions at the same time.
