StarCore, a joint venture between Agere Systems Inc., Infineon Technologies AG, and Motorola Inc. aimed at digital signal processing, has announced V4 of its DSP architecture and a series of DSPs called SC2000 based on the V4 architecture.

The architecture provides, on average, 50 percent more video processing capability while reducing power consumption by 50 percent and is intended for use in mobile electronic devices, StarCore said.

The V4 architecture includes additional single-instruction multiple-data (SIMD) instructions allow the V4 architecture to execute up to 54 elemental RISC operations per clock cycle when performing motion estimation, which is a fundamental algorithm common to all video compression standards. As a result, processors based on the StarCore V4 architecture can perform simultaneous software encoding and decoding of VGA-quality MPEG-4 video at 30fps and beyond.

Freescale Semiconductor Inc., a wholly owned subsidiary of Motorola Inc., recently collaborated with StarCore to adopt the architecture for future cellular handset products and communication infrastructure products. The StarCore architecture is currently used in Motorola's MXC platform and 2.5G, 2.75G and 3G handsets.

"The StarCore V4 architecture is ideal for a broad range of consumer electronics devices, including multimedia-enhanced wireless terminals, low- cost E-GPRS and WCDMA handsets integrating single-core wireless modems, and portable video players," said Alex Bedarida, VP of marketing for StarCore, in a statement.

The StarCore SC2000 processor family is based on a six-stage CPU pipeline that allows processors to operate at clock frequencies of up to 450MHz worst case in 90nm silicon technology and typically up to 600MHz, StarCore said. General availability of the SC2000-family cores and platforms is planned for late summer this year.
