It features a data prefetch engine , non - blocking interleaved data cache , dual floating point execution units , and many other goodies 它特有一个数据预取引擎,无阻塞的交叉数据缓存,双浮点执行单元,以及其他一些很好的设计。
Feu floating point execution unit . this performs floating point related calculations for both existing scalar instructions along with support for some of the new simd - fp instructions Feu浮点执行单元。与支持simd _ fp指令的现有规模指令一起执行浮点相关的计算。
Iu also deals with some execution units , such as comparator , alu , shifter , etc . meanwhile , iu is in charge of retiring instructions and accepting interrupts 它主要负责指令译码、指令发射、读取操作数、跳转预测检查、建立旁路、指令执行、指令退休和异常处理。
In computer engineering, an execution unit (also called a functional unit) is a part of a CPU that performs the operations and calculations called for by the Branch Unit, which receives data from the CPU. It may have its own internal control sequence unit (not to be confused with the CPUs main control unit), some registers, and other internal units such as a sub-ALU or FPU, or some smaller, more specific components.
