Intel Corp. is gearing up to go after the lucrative handheld communications business now dominated by Texas Instruments. The sector is attractive to Intel Corp. for a number of reasons, one being that success in the cell phone market would help diversify the giant chip maker and protect it from the sort of downturn it suffered last week. Intel is trying to differentiate its approach from TI’s handheld strategy, which is centered on the Digital Signal Processor (DSP) it pioneered twenty years ago. Intel is predicting that, as handhelds and PDAs merge into third generation or 3G devices, they will need more powerful Reduced Instruction Set Computer (RISC) type processors. In fact, both TI and Intel use both DSP and RISC processors in their solutions but the relative importance of the chips vary.
