Heterogeneous Multi-core Architectures

背景

介绍dark silicon现象出现的原因，晶体管富裕。

正文

• Heterogeneous Multi-core

  • Performance Heterogeneous Multi-core

    • Static Asymmetric Multi-core

      平时我们说的大小核

    • Dynamic Asymmetric Multi-core

      • coalition

        运行时联合多个小核变成大核，变成多发射（会有额外的部件来同步发射，比如内部流水会有额外的步骤来同步）

      • 能够切换多线程模式/多发射模式的CPU

  • Functional Heterogenous Multi-core

    • Graphics Processing Unit
    • Special-purpose Accelerators
      • Application-Specific Integrated Circuit
      • Application-Specific Instruction-set Processor
      • Approximate Accelerators (Neural Processing Unit)
    • Reconfigurable Computing
      • Field-Programmable Gate Arrays
      • Coarse-Grained Reconfigurable Arrays
