Q. Show the Bus and Memory Transfers?
A digital computer has many registers and rather than connecting wires amid all registers to transfer information between them a common bus is employed. Bus is a path(consists of a group of wires) one for each bit of a register, over that information is transferred from any of different sources to any of different destinations.
From a register to Bus: BUS ← R.
The transfer from bus to register can be stated symbolically as:
R1 ← BUS,
Content of the selected register is placed on BUS and content of bus is loaded in register R1 by triggering its load control input.
