ARM处理器可以节省能源和延长电池寿命，但它们可能不如x86处理器快或功能强大。
“换句话说:无论是 x86 还是 ARM ISA,实现市场期望的功能和性能都有‘典型成本’。因此,如果增加复杂性会降低任何 ISA 的功耗,那么就变成了一场争夺哪组设计选择能够产生最佳性能/功耗/面积 (PPA) 以满足消费者期望的战斗。” ARM 设计被认为比 x86 更节能,至少在它们所搭载的产品中是如此:有 Apple 自己的设...
Building a CPU is a complex business. ARM, Intel and MIPS are all working hard to bring the best technology available to mobile devices, however ARM is clearly the leader. With its focus on power efficient processors, its clean 64-bit implementation, its heterogeneous computing, and its role ...
Power Struggles: Revisiting the RISC vs. CISC Debate on Contemporary ARM and x86 Architectures 换句话说,这个非常受欢迎的Techquickie视频是具有误导性的,ARM ISA与低功耗并无必然联系。同样地,x86 ISA也并非代表高性能。我们今天熟知的基于ARM的CPU之所以功耗低,是因为ARM CPU制造商瞄准手机和平板电脑等低功耗场...
Arm-based processorswere mainly viewed as targeting the embedded market, because they offer sufficient performance while keeping power consumption low. But many hardware vendors are now using the 64-bit Arm architecture, called AArch64, to build server CPUs and to compete with the x86 architecture...
更早的Power Struggles: Revisiting the RISC vs. CISC Debate on Contemporary ARM and x86 Architectures研究则明确Arm和x86不同处理器在功耗和性能方面的差异主要源自设计目标差异,指令集本身从来不是什么重要决定因素。“指令集的差异,虽然可能会产生最终芯片设计...
对于x86的32和64位架构来说，reorder的动作最少，所以在Intel和AMD的CPU上，编写操作系统编写驱动最容易...
Traditionally, the Windows operating system is run on devices supported by Intel-based processors, with most Windows apps built to support an x86 or x64-based architecture.We're seeing Arm-based devices become increasingly popular, however, due to their pow...
X86处理器内部采用类似RISC的micro-op(出于兼容性考虑,其指令集一直属于CISC) 经典的RISC指令集也日益扩展、复杂化(Powerpc指令集(RISC)有超过230多条指令,较许多CISC指令集更为复杂) MIPS是一个经典的RISC指令集,兼具RISC设计的简洁优雅与不足: 代码密度较低; ...
