The TX99 is expected to have a clock speed of 1GHz, the companies said. It will be based on MIPS's 64-bit Amethyst core, designed for chips produced using a 0.10-micron production process.
The TX99 is fully compatible with MIPS's 32-bit core architecture, a feature that should smooth the transition from a 32-bit architecture to 64-bit.
Toshiba and MIPS will develop the TX99 processor for embedded applications such as automotive telematics, office automation, multimedia home gateways, consumer products and networking equipment.
Toshiba plans to have its first TX99 product on the market by the first quarter of 2003 and expects to have a general-use microprocessor on the market by the end of 2003.
