This from February's edition of Nikkei Electronics Asia: "The company is developing two types of ICs. The first will implement compression and decompression of image data under JPEG-2000, incorporating the wavelet conversion and entropy encoding circuits required. The more highly integrated second IC will single-chip the ARM7TDMI 32-bit reduced instruction set computer (RISC) microprocessor core from ARM Ltd of the UK, together with an interface and the first chip circuits".

Analog Devices Develops IC for JPEG-2000

Analog Devices, Inc is developing a high-efficiency coding/decoding integrated circuit (IC) to support the Joint Photographic Coding Experts Group (JPEG) 2000, the next-generation international standard for image compression. Sample shipments are scheduled to start in the second quarter of this year, with chips for digital still cameras and printers marking the firm's entry into the image processing IC sector.

Part-1 of the JPEG-2000 standard, the core portion defining encoding/decoding processing, was adopted as an international standard in December 2000. Digital still camera manufacturers are watching developments closely, recognizing that the new standard will replace existing JPEG technology. However, as the JPEG-2000 does not offer compatibility with the existing standard, manufacturers hesitate to adopt the format.

The company is developing two types of ICs. The first will implement compression and decompression of image data under JPEG-2000, incorporating the wavelet conversion and entropy encoding circuits required. The more highly integrated second IC will single-chip the ARM7TDMI 32-bit reduced instruction set computer (RISC) microprocessor core from ARM Ltd of the UK, together with an interface and the first chip circuits. The firm had commercialized an image compression chip using wavelet conversion before commencing work on JPEG-2000.
