The fetch step is the same for each instruction: 1. The CPU sends the contents of the PC to the MAR and sends a read command on the control bus 2. In response to the read command (with address equal to PC), the memory returns the data stored at the memory location indicated by the PC on the data bus 網頁BUS INTERFACE UNIT: It provides a full 16 bit bidirectional data bus and 20 bit address bus. The bus interface unit is responsible for performing all external bus operations. …
網頁The data bus, typically consisting of 8, 16, or 32 separate lines provides a bi-directional path for moving data and instructions between system components.
