Title: Computer Processor/CPU Architecture:ALU + Registers + CU Keywords: cpuarchitecture,processorarchitecture, microprocessorarchitecture, whatarchitecture ismy cpu, newcpu architecture Description: This post gives a brief introduction to the CPU architecture based on PC processors. Generally, the 3 CPU components are ALU,registers and CU. URL: https://www.partitionwizard.com/partitionmanager/cpu-architecture.html Summary: What architecture is my CPU? Many computer users may ever have asked this question. Now, here in this article, you are going to find the answer by yourself. To learn more knowledge about CPU or other computer components, it is recommended to visit MiniTool partition master website. What Is CPU Architecture？ CPU architecture referstothe designstructure of the central processingunitincludingthe processor chipset. The two primary componentsof a CPUarchitecture are ISA (InstructionSet Architecture) and microarchitecture,whichis the implementationof the ISA. The instructionsetdefinesitsdesignedCPUarchitecture basics(basiccharacteristics) suchas registercount,availableinstructions,endianness,andOpcodessyntax,the interface/contract betweenthe CPU(hardware) andthe programmer(software).Unlessthere isaninternal bottleneck unalleviated,the ISA won’tinfluence the CPUperformance thatisaffectedbythe microarchitecture. For example,X86,MIPSand ARMCPUs are suchkinds. The microprocessor architecture defineshow the ISA controlleddesignisappliedinthe real processor architecture (processorinternal working),includingsandybridge,skylake,zen,etc.all of whichare part of x86.
