What is Omega Switching Network in Computer Architecture


Omega switching network is one such topology that is shown in the figure. In this configuration, there is directly one direction from each source to any specific destination.

There is some request design, however, cannot be linked together. For example, any two sources cannot be linked together to destinations 000 and 001.

As shown in the figure, a specific request is started in the switching network through the source that sends a 3-bit pattern depicting the destination number.

Each level checks a multiple bit to specify the 2 x 2 switch setting as the binary design transfer through the network. Level 1 determines the most essential bit, level 2 determines the middle bit, and level 3 determines the least important bit.

When the request occurs on the input 2 x 2 switch, it is finished to the lower output if the stated bit is 1 or to the upper output if the stated bit is 0.

The source is treated to be a processor and the destination is treated as a memory module in a fast coupled multiprocessor system. The direction is set when the first pass is through the network.

If the request is read or write the address is shared into memory, and therefore the information is transferred in either control using the following passes.

Both the destination and the source are treated to be processing components in a loosely coupled multiprocessor system. The source processor sends an address to the destination processor once the route is created.
