这是否意味着Intel需要在指令执行前多一个步骤、多一些晶体管、多一些能耗来执行μop的拆分操作呢?这是此前不少人谈论CISC不行的一大论据。 Arm的解码开销也不小 从Chips and Cheese的解释来看,现代Arm指令集CPU也需要执行切分μop的操作。而且对不少Arm处理器...
Cortex-A15最早在2010年发布,基于32位ARMv7-A架构。A15和A9同样具备乱序执行,但是Cortex-A15具备(两倍)的指令发射端口和执行资源,指令解码能力也要高出50%,动态分支预测能力更强(采用了多层级分支表缓存),指令拾取带宽更强(128 bit vs 64 bit),这些都能让A15的流水线执行具备更高的效率。除此以外,A15采用了VF...
Ampere Computing 于12 月推出了其 AmpereOne Arm 服务器 CPU (但本周公布了更多信息),但略有不同。这款新的“M”版本没有采用标准 AmpereOne 的 8 通道内存,而是增加了 12 通道内存。这一插槽升级使其功能更接近AMD EPYC 9005 Turin和Intel Xeon 6900P。让我们来看看这次发布的产品。 AmpereOne M 为其 A...
ISA Doesn’t Matterchipsandcheese.com/2021/07/13/arm-or-x86-isa-doesnt-matter/ 过去的十年里,ARM CPU 的制造商一直在尝试进军高性能 CPU 市场,因此我们看到了很多关于 ARM 所做的工作的文章、视频和讨论。其中许多文章都在讨论两种指令集架构(ISA)之间的差异。 本文将综合已经发表的文章、CPU 领域专家...
