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