Integrally, the RISC CPU has BIU(Bus Interfacing Unit),IDU(Instruction Decoding Unit)-. ALU(Arithmatic&logic Unit),MMU(Memory Management Unit) etc.
从整体方面来说，整个微处理器大致分为BIU(总线接口单元)、IDU(指令译码单元)、ALU(算术逻辑单元)、MMU(存储管理单元)等等。

As with instruction decoding, the execution of these instructions does not make use of the system buses.
按照指令译码的结果，这些指令的执行不会用到系统总线。
It also maintains an instruction cache for improved performance by storing the "micro operations" of the original x86 system (which can be fetched later without the overhead of decoding).
它还通过存储原始x86系统的“微操作”来维护指令缓存(其后可在没有解码开销的情况下提取)，进而改进性能。
