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