What does cache coherency actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

The answer is Cache Coherency. Shared memory systems implement a coherence protocol for this purpose. Coherency seeks to make the caches of a shared-memory system functionally available to all the ...

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To ...

A fundamentally new approach to cache coherence has been released -- the first in more than three decades. Whereas with existing techniques, the directory's memory allotment increases in direct ...

How Cache Coherency Impacts Power, Performance Part 1: A look at the impact of communication across multiple processors on an SoC and how to to make that more efficient.

That outline of cache coherence is Interesting, but even today I/O-attached accelerators can access an SMP’s memory. Most (all?) will even be able to read the contents of the SMP’s cache when pulling ...

In the first part of this series on the proposed Cache Coherence Interconnect for Accelerators (CCIX) standard, we talked about the issues of cache coherence and the need to share memory across ...

At the International Conference on Parallel Architectures and Compilation Techniques in October, MIT researchers unveil the first fundamentally new approach to cache coherence in more than three ...

Cache memory significantly reduces time and power consumption for memory access in systems-on-chip. Technologies like AMBA protocols facilitate cache coherence and efficient data management across ...

How Cache Coherency Impacts Power, Performance Second of two parts: Why and how to add cache coherency to an existing design.
