DOW JONES NEWSWIRES Xilinx Inc.'s (XLNX) fiscal first-quarter profit fell 2.7% as higher operating expenses cut into the programmable-chip maker's margins. Shares were off 2.2% at $32.46 after-hours Wednesday, though the company reported better-than-expected revenue. The stock had climbed 17% over the past year through the close. Xilinx--which makes chips used in cellphone base stations, network routers, DVD players and cable modems--has reported strong revenue growth over the past year on climbing sales to the communications end-market, its largest top-line contributor.

Gross margin narrowed to 63.7% from 65% amid higher costs. Sales of new products jumped 35% on strong demand for its models in its Virtex-6 and Spartan-6 families.
