摘要: UItraSpare I is a second-generation superscalar processor. It high performance, highly integrated, four issue processor based on the Spare Version 9 64-bit RISC architecture. We have extended core instruction set to include graphics instructions that provide most common operations related two dimensional image processing; two- and three-dimensional compression algorithms; parallel pixel data with 8-, 16-, 32-bit components. Additional, new memory access support very bandwidth requirements typical of multimedia applications.
