CAST Rolls Out Flexible Family of JPEG Image Processing Cores

2/9/2004 - Semiconductor intellectual property (IP) provider CAST, Inc. announced a new flexible family of JPEG image processing cores that gives greater choice in matching the characteristics and cost of a JPEG-standard core with an applicationís specific requirements.

The CAST Flexible JPEG Family starts with new baseline JPEG cores that provide inexpensive image compression and decompression in conformance with the JPEG standard. Designers can add one or more additional options, in any combination:

A core combining all these options, JPEG Super, completes the CAST Flexible JPEG Family. All the cores are suitable for use in ASICs or FPGAs. Select cores are available now, the rest in the second quarter. Pricing varies; contact CAST for details.

About the New Cores
JPEG is an image compression algorithm popularly used for photographs and other naturalistic images (see CASTís JPEG cores all provide baseline compliance with the ISO/IEC 10918-1 JPEG standard, but this standard includes options that arenít all needed for every application.

The base CAST JPEG coder, decoder and codec cores are delivered in a fixed configuration as specified by the customer. An encoder, for example, might be configured to only work with grayscale images sized 640 x 480 pixels and to use pre-set encoding options (like Huffman and quantization tables). This contrasts with most competing cores ó and CASTís JPEG Super cores ó which offer full programmability and a complete set of processing capabilities whether these are actually needed or not.

CASTís base JPEG cores process images sufficiently fast for applications such as inexpensive digital cameras or frame-per-minute surveillance systems. If quicker processing is required ó as for high-end digital cameras ó the customer can add the Speed option.

If video processing is required, the customer would add the Motion option, perhaps by itself for a consumer video conferencing product or with Speed as well for a real-time video conferencing system. Likewise, if the core is to handle a variety of frame sizes, quality levels, and so on, then the Program option is the best choice.

All the cores are developed by CAST partner Alma Technologies, based in Greece (
