Is there really such a thing as a "DSP" anymore?

The use of a traditional signal processing device like a digital signal processor (DSP) has been limited to lower-volume complex wireless systems, as higher-volume wireless products tend to use more integrated programmable system on a chip technologies. The emergence of multicore devices combining the functionality of ASSPs, GPPs, DSPs, and FPGAs into a single offering complicates the design choices in radio systems. The development team for any new advanced wireless product must now spend considerable effort evaluating whether a radio function traditionally performed on an ASIC would be better implemented differently. Design choices are expected to become even more difficult as the competition tighten between DSP and FPGA vendors in the various segments of the wireless markets
