In another decline by a major chipmaker, National Semiconductor (NSM) today posted lower third-quarter earnings from a year ago and warned of falling revenue with the likelihood of a loss in the next reporting period. The company blamed part of its dismal report on its Cyrix subsidiary, which was bought in November. In connection with the purchase of the chipmaker, National recorded a one-time charge of $30 million. "As we indicated on February 2, market conditions due to the Asian economic crisis and difficulties in ramping up adequate volumes of new products in our recently acquired Cyrix subsidiary impacted our results in the quarter," chief executive Brian Halla said in a statement. "As a result of this uncertain business environment, we are aggressively pursuing cost reduction actions and obviously continuing to drive revenue growth for the future."
