The interpretation is carried out by the instruction decoder. 该翻译借指令译码器来进行。
CPU caches mark referenced memory as code or data depending upon whether it is sent to an instruction decoder. CPU缓存像标记代码和数据一样标记被引用的内存,是依靠判断它是否被发送到指令解码器。
Although they are not shown in this diagram, there would be control lines from the instruction decoder. 尽管图中没有显示,但指令译码器还有下列功能的控制线。
Propose the run time dispatched instruction decoder and issue logic based on instruction execution cycle. 提出基于指令类型动态分配的译码器设计方案和基于指令执行周期的动态逻辑发射方案。
During the test, some problems of the algorithm were found, and then an improved method was given and it removed the feature of instruction bundle, supplied a unique virtual address to each instruction on which the decoder acted. 根据测试中发现该算法存在的问题,提出了改进方案,消除束的特性,给每条指令赋予唯一地址并按此地址进行解码。
The key of this design is the design of instructions state machine. Every instruction cycle includes 8 machine clock cycles, is made up of fetch instruction, decoder instruction, execute instruction, writing RAM, writing register and reading RAM etc. 本设计的关键点为指令执行状态级的设计,每个指令周期包括8个机器时钟周期,由取指、译指、执指、RAM读、寄存器写、RAM写等组成;
