Northern Ireland-based Amphion Semiconductor Inc, a provider of semiconductor intellectual-property for digital video and broadband wireless system-on-a-chip (SoC) design, has extended its CS6700 series of high performance cores for low power MPEG-4 enabled applications with an advanced modular accelerator-based solution for real-time MPEG-4 video compression.

Designed for ultra-low power operation and easy system-level integration into processor-based SoC and platform solutions, the Amphion CS6701 MPEG-4 'Simple Profile' Video Encoder incorporates hardware blocks for the acceleration of key compute-intensive MPEG-4 video compression algorithms, including motion estimation. The same modular architecture is performance-scaleable to more compute-intensive MPEG-4 profiles, such as 'Advanced Simple Profile' (ASP).

Key component blocks for motion estimation, bitstream packing, pixel compression, and video pre-processing are also available as standalone hardware-accelerator cores for the rapid development of MPEG-4 systems-on-silicon.

"This is a truly scaleable, modular architecture for MPEG-4 encode that's equally adaptable for use in power-sensitive consumer electronics and high-end professional broadcast markets," says Stephen Farson, vice president of engineering at Amphion. "The CS6701 is a compact design that requires the absolute minimum of on-chip processor and memory support, yet delivers QCIF and CIF performance with no compromises on picture quality."
