INSILICON'S JPEG2000 ENCODER ACCELERATES AND OPTIMIZES NEXT GENERATION IMAGE COMPRESSION.inSilicon Corporation (Nasdaq:INSN INSN International Nepal Solidarity Network ) -- a provider of communications technology for complex systems-on-chip -- has announced the release of their newest image compression semiconductor intellectual property, the JPEG JPEG in full Joint Photographic Experts Group Standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. 2000 Encoder. JPEG2000 is the latest still image compression standard available today, designed to increase the compression ratio and quality of digital still images and text, while maintaining the 24-bit color and multi-platform compatibility advantages of the current JPEG standard. An approved ISO/ITU-T international standard since January 2001, JPEG2000 is targeted for the rapidly growing consumer, networking, and PC peripheral applications, including next-generation digital cameras, scanners, and wireless imaging devices. IDC, a leading information technology organization, projects 39 million digital cameras will ship annually by 2005. And InfoTrends Research Group, another leading information technology organization, projects over 24 million scanners will ship in 2006. Employing the reversible 5/3 wavelet (mathematics) wavelet - A waveform that is bounded in both frequency and duration. Wavelet tranforms provide an alternative to more traditional Fourier transforms used for analysing waveforms, e.g. sound. transformation algorithm, inSilicon's JPEG2000 Encoder compresses digital images at ratios exceeding 50:1. This enables on-the-fly, lossy See lossy compression. (algorithm) lossy - A term describing a data compression algorithm which actually reduces the amount of information in the data, rather than just the number of bits used to represent that information. and lossless compression schemes, allowing system designers to optimize between image compression quality and downloading time. Compared to JPEG, JPEG2000 has superior, low bit-rate compression, and is error resilient in noisy environments such as mobile web browsing. In mobile applications, the improved controls for image resolution and web browsing in JPEG2000 allow users to quickly view a set of images and download the desired image. The inSilicon JPEG2000 Encoder is portable to any ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. or FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. technology and is designed for embedded application implementation with efficient gate count and low power consumption. The encoder supports four programmable quantization (1) The division of a range of values into a single number, code or classification. For example, class A is 0 to 999, class B is 1000 to 9999 and class C is 10000 and above. (2) In analog to digital conversion, the assignment of a number to the amplitude of a wave. tables, allowing on-demand configuration of compression ratios. The JPEG2000 Encoder supports packet header processing to minimize the overhead packet-processing requirements. For fast system-on-chip integration, the encoder includes a simple CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. interface, providing easy access to all configuration options. "As image files become larger, the need for portable devices to provide efficient, high-speed data compression is absolutely essential to satisfy the needs of the end user," said Jack Lim, product marketing manager of inSilicon. "As an example, a JPEG2000 hardware-based system allows the high-speed compression and decompression of high resolution digital photos to a camera or PC in seconds. In comparison, a JPEG software-based system would take several minutes, with much lower picture quality." Hardware designers receive Verilog RTL (Register Transfer Level) A high-level hardware description language (HDL) for defining digital circuits. The circuits are described as a collection of registers, Boolean equations, control logic such as "if-then-else" statements as well as complex event sequences; source code, Verilog behavioral models, a comprehensive test suite, synthesis scripts, and documentation for integrating the JPEG2000 Encoder into a system-on-chip. The JPEG2000 Encoder is available today, with a full JPEG2000 CODEC available this fall. Contact inSilicon for pricing information. |
