Question

what is mulitple bus organization…?

Answer 1

The single-bus organization, which is only one of the possibilities for interconnecting different building blocks of CPU. An alternative structure is the two busstructure, where two different internal buses are used in CPU. ... There is a special arrangement to transfer the data from one bus to the other bus.

Answer 2

So far we have considered only one internal bus of the CPU. The single bus organization, which is only one of the different interconnection possibilities CPU building blocks.

An alternative structure is the two bus structure, wherein two different internal buses are used in the central unit. All register outputs are connected to the bus A, add all registered entries are connected to the bus B.

There is a special arrangement for transferring data from one bus to another bus. The buses are connected by the bus link G. When this link is activated on the data bus A is the transfer to the bus B. When G is disabled, the two buses are electrically isolated.



Because the two buses are used here, the temporary register Z is not necessary here, which is used in the organization of single bus to store the result of the ALU. Now, the result can be transferred directly to the bus B, as one of the inputs is disabled bus A. With the bus link, the result can be directly transferred to the destination register.

Hope this helps you....
