• 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...
  • Cache coherency in big.little system.
    Within an arm system, a cluster is an ACE master connected to the Arm CCI. To keep the cache coherency, the cluster would send some transactions to the bus and are trapped by the snoop filter of CCI....
  • General Feature of Cortex processors on cache coherency
    Hi Experts, Is there any general feature available in the cortex processors to realize the cache lines by DMA through AXI ? I found some features like CCI module available to provide this feature in multi...
  • 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...
