• Cache Coherence
    Hi ,    I am working on ARM Multiprocessor. The Following is scenario for Cache coherency . Please let me know if it is valid.    1. Bring Core 1 out of reset.    2. Bring Core 2 out of reset.    3. Invalidate...
  • Extended System Coherency: Part 1 - Cache Coherency Fundamentals
    Chinese Version 中文版： 扩展系统一致性 - 第 1 部分 - 缓存一致性基本信息 Introduction The theme of TechCon 2013 was “Where intelligence connects” and in many ways hardware system coherency is an important part of connecting...
  • Is Cache Stashing introduced in DynamIQ similar to IO coherency?
    IO coherency also allows device to access coherent memory space. The only difference I noticed is that cache stashing connects device directly with cluster, however, IO coherency transactions need to...
  • Cache cleaning and invalidating in ARM Cortex-A
    Cleaning or invalidating the L1 cache and L2 cache will not be a single atomic operation. A core might therefore perform cache maintenance on a particular address in both L1 and L2 caches only as two...
