Storing a word in memory - computer architecture, Computer Engineering

Assignment Help:

Storing a word in Memory:

That is similar process with fetching a word from memory.

The required address is loaded into the MAR
After that data to be written are loaded into MDR, and a write command is issued.
If we suppose that the data word to be stored in the memory is in R2 and that the memory address is in R1, the Write operation needed the following sequence:
MAR - [R1]
MDR -[R2]
Write
Wait for the MFC

Move R2, (R1) requires the following sequence (signal):

R1out, MARin

R2out, MDRin. Write

MDRoutE,WMFC
