Xilinx公司与加拿大Xelltex公司不久联合发布了用于Virtex—E和Spartan—Ⅱ现场可编程门阵列的新产品AllianceCORE。该技术包括正反离散余弦变换(DCT和IDCT)和一个JPEG编解码器。正反离散余弦变换技术支持Virtex、Virtex—E和Spartan—Ⅱ设备,JPEG编解码器也支持Virtex、Virtex—E设备。专为此项新技术开发的目标应用程序包括图像存储、数据和影像压缩、医学成像及工业系统。正反离散余弦变换的核心是在杜比AC2、AC3、JPEG以及
Xilinx and Canadian company Xelltex recently unveiled AllianceCORE, a new product for Virtex-E and Spartan-II field-programmable gate arrays. The technique includes forward and inverse discrete cosine transform (DCT and IDCT) and a JPEG codec. The inverse and inverse discrete cosine transform technology supports Virtex, Virtex-E and Spartan-II devices, JPEG codecs also support Virtex, Virtex-E devices. Target applications developed specifically for this new technology include image storage, data and image compression, medical imaging and industrial systems. The core of the DCT is the Dolby AC2, AC3, JPEG as well
