Memory contention in bus-oriented systems

[bestdev]

Memory contention can still arise in two ways in bus-oriented systems.

1) There may be some congestion in the connection hardware. This will vary considerably depending on the technology used in the connection hardware.

2) Memory contention can arise is when two or more processors are accessing the same memory module within a short time interval. Each memory module services memory requests sequentially, and has only one memory controller that services requests at a certain speed. Therefore, concurrent requests by different processors to the same memory module will cause delays.
