UMA Bus-Based SMP Architectures

UMA Bus-Based SMP Architectures. The simplest multiprocessors are based on a single bus. Two or more CPUs and one or more memory modules all use the same bus for communication. If the bus is busy when a CPU wants to read memory, it must wait. Adding more CPUs results in more waiting.
