COMPUTER OR GANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION A multicore computer, also known as a chip multiprocessor, combines two or more processors (called cores) on a single piece of silicon (called a die). Typically, each cor…

多核处理器也称片上多核处理器(Chip Multi-Processor,CMP). 1.多核处理器的流行 多核出现前,商业化处理器都致力于单核处理器的发展,其性能已经发挥到极致,仅仅提高单核芯片的速度会产生过多热量且无法带来相应性能改善,但CPU性能需求大于CPU发展速度.尽管增加流水线提高频率,但缓存增加和漏电流控制不力造成功率大幅增加,性能反而不如之前低频率的CPU.功率增加,散热问题也严重了,风冷已经不能解决问题了. 那么新技术必须出现-多核处理器.早在1996年就有第一款多核CPU原型H…

Various embodiments of methods and systems for thermally aware scheduling of workloads in a portable computing device that contains a heterogeneous, multi-processor system on a chip ("SoC") are disclosed. Because individual processing components…

An embodiment provides a virtual address cache memory including: a TLB virtual page memory configured to, when a rewrite to a TLB occurs, rewrite entry data; a data memory configured to hold cache data using a virtual page tag or a page offset as a c…

Minimizing the overall power conservation in a symmetric multiprocessor system disposed in a system-on-chip (SoC) depends on using voltage islands operated at different voltages such that similar circuits will perform at significantly different level…

COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION An SMP operating system manages processor and other computer resources so that the user perceives a single operating system controlling system resources. In fact, such a c…
