PPT-1 Parallel and Multiprocessor Architectures – Shared Memory

Recall Microprocessors are classified by how memory is organized Tightlycoupled multiprocessor systems use the same memory They are also referred to as shared memory multiprocessors The processors do not necessarily have to share the same block of physical memory . Hardware Parallelism. Computing: execute instructions that operate on data.. Flynn’s . taxonomy (Michael Flynn, 1967) classifies computer architectures based on the number of instructions that can be executed and how they operate on data.. : Rethinking the Multicore Memory Hierarchy. for Disciplined Parallelism.
