NEC Corporation and its wholly owned subsidiary in the United States, NEC Electronics Inc., today announced it has developed an 800-megahertz (MHz) 64-bit MIPS® microprocessor core, code named Sapphire, based on NEC's Vr5500(TM) 64-bit out-of-order superscalar microprocessor architecture. Developed using NEC's 0.13 micron (um) copper process technology, the new Sapphire core executes up to 1600 Dhrystone million instructions per second (MIPS) at 800 MHz. For low-power applications, the core executes 1200 Dhrystone MIPS while operating at 600 MHz and consuming power of only two watts (W). NEC also announced it is developing its next-generation Sapphire core, code named Star Sapphire, which enables operation at one gigahertz (GHz). The new Star Sapphire core will use NEC's 90 nanometer (nm) process and features various micro-architecture enhancements including vector operations and single-instruction multiple data (SIMD).
