  • page table Cachability bit effect!

    Hi experts,

    I really get confused with the page table cachability bit (c bit) effect (Cortex-A8) and need your help to find answer of my question. The questions is whether page table C-bit only controls writing/updating into the cache(inner or outer) lines…

  • Cache and store buffer maintenance in cortex-a8!

    Dear All,

    Technical data sheets for the ARM7500FE  and ARM7100 say that:

    "In the ARM Processor the cache will be searched regardless of the state of the C bit, only reads that miss the cache will be affected."

    Now the question is that whether…
