The OMAP architecture from Texas Instruments leads the way toward a dual-core computing paradigm for a world of ubiquitous information. The combination of a DSP and RISC unit on one chip provides a basis for the development of all kinds of devices that need to process digital signals while they run conventional code in parallel, especially when power is limited. Next-generation handsets are a convenient example of this approach, where a DSP handles the repetitive processing demands of voice and media streams while control and conventional application code runs concurrently on the RISC core. But the usefulness of the multi-core, system-on-a-chip idea goes much further.
