DigiTimes had an interview with Casey Springer, product manager of IDT, about dual-core chips in handsets.
A: Since handsets are now featuring stronger multimedia content management capabilities with some housing even stronger multimedia functionality than conventional consumer electronics, such a trend has prompted chip supplier to offer dual-processor solutions to fit the life cycle and nature of handsets.
Under a dual-processor platform, one processor is responsible for signal processing while the other deals with multimedia content execution. Since this design principal could also enhance the production efficiency of downstream handset makers, dual-processor handsets are now drawing popularity among customers. Having handsets with dual-processors is now a key for vendors to supplement "value-added" solutions for customers.
