Common features of programmable DSP architectures

Most modern digital signal processing (DSP) architectures are significantly more irregular than their general purpose computing counterparts, and certainly more complex than most 8/16 bit microcontroller architectures. This is due, in part, to the need to pack high levels of computational power into the processor design to handle the computational demands of many DSP workloads. At the ...
