Toshiba America Electronic Components (TAEC) has topped off its MIPS-based microprocessor line with a 64-bit single-chip RISC processor that, for the first time, employs Toshiba's TX99/H4 CPU core and 90nm process technologies.

The simultaneous execution of two instructions is enabled by the device's seven-stage superscalar pipeline architecture. The microprocessor, which is designated as the TX9956CXBG, features a 533MHz to 666MHz operating frequency.

TAEC said it expects the microprocessor will be utilized in multifunction printers and high-end STBs as well as in a range of diverse applications.

The company noted that the device is scalable from earlier microprocessors and product developers can upgrade from low frequency processors and keep and use same companion ASICs or off-the-shelf SysAD-compatible chip sets. The seven-stage superscalar pipeline architecture was jointly developed by Toshiba and MIPS.

The RTOSs that are planned for use with the device include MontaVista Linux from MontaVista Software Inc., and VxWorks from Wind River Systems Inc.

Volume production for the 64-bit processor is planned to begin in November.
