Broadway is the codename of the 32-bit Central Processing Unit (CPU) used in Nintendo's Wii video game console. It was designed by IBM, and is currently being produced using a 65 nm SOI process. According to IBM, the processor consumes 20% less power than its predecessor, the 180 nm Gekko used in the Nintendo GameCube video game console. ''Broadway'' is being produced by IBM at their 300 mm semiconductor development and manufacturing facility in East Fishkill, New York. The bond, assembly, and test operation for the Broadway module is performed at the IBM facility in Bromont, Quebec. Very few official details have been released to the public by Nintendo or IBM. Unofficial reports claim it is derived from the 486 MHz Gekko architecture used in the GameCube and runs 50% faster at 729 MHz.〔(Wii Technical Specification, Wii )〕 The PowerPC 750CL, released in 2006, is a stock CPU offered by IBM and virtually identical to Broadway. The only difference is that the 750CL comes in variants, ranging from 400 MHz up to 1000 MHz.〔(IBM Broadway RISC Microprocessor User’s Manual, v0.6 ) (page 361)〕〔(IBM PowerPC 750CL Microprocessor Revision Level DD2.x )〕〔(IBM PowerPC 750CL RISC Microprocessor User’s Manual )〕 ==Specifications== * 90 nanometer process technology, shrunk to 65 nm in 2007. 〔http://www.neogaf.com/forum/showpost.php?p=47873023&postcount=205〕 * Out-of-order execution Power Architecture core, specially modified for the Wii platform * IBM silicon on insulator (SOI) technology * Backward compatible with the Gekko processor * 729 MHz * 32-bit integer unit * 64-bit floating-point (or 2 × 32-bit SIMD, often found under the denomination "paired singles") * 64 kB L1 cache (32 kB instruction + 32 kB data) * 256 kB L2 cache * 2.9 GFLOPS 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Broadway (microprocessor)」の詳細全文を読む スポンサード リンク
