Processor highly specialized for the fast operational needs of digital signal processing are termed as a DSP. These processors specialize in dealing with signals represented in large chunks of digital data and near real time processing of Signal Modeling tasks like Convolution, Transfer Functions and Frequency Responses and Signal Processing Tasks like Estimations, Filtering etc. General purpose processors too are capable of implementing such algorithms, but have latency problems in the absence of a optimized hardware solution. A DSP may come in the form of a dedicated IC or as a FPGA.
