System Bus and Memory Transfer Computer Organization and Architecture by Ravinder Nath Rajotiya - March 15, 2021December 9, 20220 Bus and Memory Transfer: Introduction: as discussed in the beginning of this chapter that the micro-operation are the operations, such as the transfer, performed on the data stored in the registers. A simple system may contain few registers and the mechanism can be very simple as described below in the register transfer notation: T1 : R2 <-- R0 T3: R2 <-- R1 The two statements have a common destination but two different sources of data. Either the content of R0 or R1 is loaded in R2. Registers shown in figure are 1-bit in length (i.e. FF), however they will be of size in multiple of bytes. For this simple case we can employ a 2x1 MUX to perform the transfer operation described register=transfer notation.. Bus
