Digital signal processors (DSPs) have played an integral role in the transition of the telecommunications network from an analog-dominated network exclusively dedicated to voice communications to a modern digital multimedia network. In recent years, the network’s media gateways and the DSPs that are at their core have taken several new steps in their evolution. This white paper examines the evolution of media gateways, the role that TI’s DSP technology has played in this and how the emergence of the network coprocessor (NetCP) is currently altering the makeup of next-generation media gateways.
