Question

Explain the memory operation for DRß M[AR]​

Answer 1

Explanation:

There are two key operations on memory: fetch( address ) returns value without changing the value stored at that address. store( address, value ) writes new value into the cell at the given address.

Answer 2

Memory operation:

Explanation:

Memory opertion:

Memory operation sre per second or MOPS is  metric for a expression of performancecapacity semiconductor memory. It can also be use to examine  efficiency of RAM  the Windows operating environment.itcan be affected due to multiple applications due to open at once without adequatejob scheduling.

Memory operation for DRß M[AR]​:

• The transfer of the information from  memory of the word to the outside environment is known as read operation.

• The transfer of the  new information thet need to be stored in the memory is known as write operation.
• Consider an memory unit that has receivesthe address from a to the register, known as the address register, symboliz by AR
• The data are to be  transferred to another register, called the data register, and  symbolized by DR . The read  in the operation can be stated as write as  follows: Read: DR ← M[AR]
• This causesing  a transfer of the information into the DR from the memortword M the selected by the address in AR .
• The write the  operation transfers  content of a data register to a memory word M selected the address. Assume that in the input data are in register R1 R3 ← R1 + R2 + 1. R2 is as  the symbol for the 1's complement of R2.
