The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a running program. On the other hand, the physical address is a location that exists in the memory unit, and can be accessed physically. 逻辑地址和物理地址的基本区别是,逻辑地...
现代处理器使用的是虚拟寻址的方式,CPU 通过访问虚拟地址(Virtual Address),经过翻译获得物理地址,才能访问内存。这个翻译过程由 CPU 中的内存管理单元(Memory Management Unit,缩写为 MMU)完成。 具体流程如上图所示:首先会在 TLB(Translation Lookaside Buffer)中进行查询,它表位于 CPU 内部,查询速度最快;如果没有命...
我们可以总结指令的一生:fetch, decode, dispatch, issue, execute, finish, complete, and retire.其中issue是进入function unit开始执行的时刻,finish是离开function unit的时刻。 总结超标量处理器 超标量处理器实现了指令的并行,让处理器性能更进一步。 同时也了解了我们常说的"CPU乱序执行"到底是怎么一回事(上面的...
CPU resource用cpu unit来计量,在kubernetes中1个CPU Unit等于1个物理CPU core或者1个虚拟CPU core(1 physical CPU core, or 1 virtual core),取决于这个node是物理主机还是虚拟机。 CPU resource的计量可以使用小数,例如一个容器的spec.containers[].resources.requests.cpu=0.5,表示申请占用一半的cpu time。 为避...

The unit is DCLK, and the value ranges from 1 to 4095. NOTE: This parameter is available only when CKE Power Down is set to Enable. 20 Memory Test Sets whether to enable the memory test during fast boot. The options are as follows: Enable Disable Enable Warm Boot Fast Support ...
首先,in memory area是独立于传统的SGA和PGA的单独的内存空间,由1Mpool和64Kpool两部分构成。其中1M pool用于保存列格式的数据,IMCU(in memoryCompressionUnit)是基本的存储单位;64Kpool用于保存和IMCU相对的元数据信息,SMU(SnapshotMetadataUnit)是这部分内存的基本单位。读者可以通过下面的查询了解相关的信息。

CPU vs RAM: which is more important? The central processing unit (CPU) is your computer’s nerve center, where all the calculations necessary to run software applications are carried out. But, in order to function quickly and smoothly, CPUs rely on RAM to provide high-speed access to the ...
Everything here except for the store buffer uses undocumented counters/unit masks However, Kaby Lake can keep more independent operations in flight with its 224-entry reorder buffer. Basic FP operations on Kaby Lake generally have a 4-cycle latency compared to 5 cycles on Bulldozer, so Kaby Lak...
