In this article, we will discuss about theCache Coherence Problem and its different protocols in Computer Architecture. Submitted byUma Dasgupta, on March 08, 2020 First of all, we will try to understand whatca
Coherence Protocols What Is Cache Coherence? To begin with, what is cache coherence? In computer architecture, cache consistency is the unity of shared resource data, and the resource is ultimately stored in multiple local caches. When the client in the system maintains caches of common memory re...
Cache Coherence in Parallel Computer Architecture - Explore cache coherence mechanisms and synchronization techniques in parallel computer architecture to ensure data consistency across processors.
Cache consistency in computer architecture refers to the contract between the programmer and the memory system regarding the synchronization and ordering of memory operations in a cache-coherence scheme. It is different from the concept of cache coherence and consistency models. ...
Memory Models for Embedded Multicore Architecture Cache coherency Multicore systems may have several levels of memory cache as shown in Figure 4.8. To maintain consistency and validation of data, cache coherence protocols, provided by the processor, must be used. For example, consider the situation...

Directory-based coherence: In a directory-based system, the data being shared is placed in a common directory that maintains the coherence between caches. The directory acts as a filter through which the processor must ask permission to load an entry from the primary memory to its cache. When...
