Give example of bus and memory transfer
For example, the read operation for transfer of a memory unit M from address register AR to another data register DR can be illustrated as:
Read: DR ←M [AR]
The write operation transfer contents of a data register to a memory word M selected by address. Assume that input data are in register R1 and address in the AR. The write operation can be stated symbolic as belwo:
Write: M [AR] ← R1
This cause a transfer of information from R1 into memory word M selected by address in AR.
