Bus contention
Bus contention occurs when more than one device tries to place values
on a single shared channel at the same time. This is addressed with
network on chip (NoC) designs.
Contention on a bus requires arbitration, which may dramatically
increase the number of cycles required for an operation.
A bus arbiter arbitrates requests from multiple masters to determine
which block may read or write. It can support multi-threading through
atomic compare-and-swap operations.
