WebNov 18, 2024 · Memory consistency is one of the key elements for multicore systems that share the same memory and that use a hierarchy of caches. Thanks to it, all cores have consistent access to memory and have a common view of the memory they use to run programs. We explain how it works and what is its usefulness.

WebApr 6, 2024 · Abstract: We solve the two challenges architects face when designing heterogeneous processors with cache coherent shared memory. First, we develop an automated tool, called HeteroGen, for composing clusters of cores, each with its own coherence protocol. Second, we show that the output of HeteroGen adheres to a … Web3.2 Cache Coherency. Cache coherency is a situation where multiple processor cores share the same memory hierarchy, but have their own L1 data and instruction caches. Incorrect execution could occur if two or more copies of a given cache block exist, in two processors’ caches, and one of these blocks is modified.
