Amphion Semiconductor Inc. has developed ASIC- and FPGA-targeted versions of its hardware-accelerator cores for MPEG-4, MPEG-2, and JPEG2000 compression with advanced high-performance bus (AHB) interfaces compatible with the AMBA specification for on-chip system bus connectivity.

The AHB interfaces allows Amphion cores to be used in AMBA-based SoC designs, such as those using RISC microprocessor cores from ARM and other processor IP providers.

"With AHB-ported cores for MPEG-4, MPEG-2 and JPEG2000, Amphion corners the market for SoC-ready solutions for three key consumer-focused compression technologies. Chip designers, EDA vendors, and third-party IP providers are converging on AMBA AHB connectivity to the point where it is one of the most widely used on-chip system bus scheme," claimed Stephen Farson, VP of Engineering at Amphion, commented

AMBA prescribes an on-chip bus infrastructure for the interconnection and protocol-driven networking of peripheral IP and functional blocks with embedded processors. These system-level components are typically combined in SoC designs to integrate complex silicon platforms for digital convergence products.

The CS6701 MPEG-4 video encoder and the CS6551A MPEG-2 video decoder are among the first of Amphion's cores to support on-chip bus interconnectivity in compliance with the AMBA specification.

Also ported for AHB is the CS6510 JPEG2000 encoder, which carries out computationally-intensive tasks such as wavelet transform, entropy coding, quantization, and data scheduling, freeing the on-chip embedded processor to control value add tasks such as user interface management and data formatting.

Fully compliant with the ISO/IEC 15444-1 standard, the CS6510 performs full-motion image encode at rates up to 60MSa/s in 180nm process technologies.
