Cyrix, recently acquired by National Semiconductor, has confirmed it will announce the design for its next generation of processors at the Microprocessor Forum this autumn.
But silicon will not start to be available until next year, said Brendan Sherry, general manager of Cyrix Europe.
He said: "We?ve been pretty open about our plans for the future and the M3 has been on our roadmap for some time. We?re talking architecture here, not silicon. Our design team has been working on it [the M3] for as much as two years."
He said the Cyrix strategy fitted into Nat Semi?s plans to introduce so-called ?systems on a chip? that will run at high clock speeds.
"Very shortly we?ll introduce our Media GX processor with full MX capability," said Sherry. "If you want 400MHz, 500MHz, 600MHz and speeds above, you need a faster core. That?s clearly pivotal to produce a system on a chip."
He discounted US reports that the Cyrix-IBM joint agreement to produce silicon was in any danger. He said that the agreement Cyrix has with IBM runs to the end of December 1999 and is renewable.
While Nat Semi will be able to produce Cyrix chips he believes it is unlikely that will start to happen in any volume until next year.
