The Fetch-Execute Cycle的中文翻译 The Fetch-Execute Cycle 获取执行周期
A computer program consists of a collection of instructions encoded in the binary numbering system. The stages of the fetch execution cycle are the sequence of steps followed by the Central Processing Unit (CPU) as it executes instructions and functions.
The functional block diagram or architecture of a microprocessor chip is shown in figure 3.1 (based on the Intel 8085 CPU). The CPU has an internal 8-bit bus (described here as a data bus although it is sometimes used for other purposes) along which information internal to the CPU flows,...
