• Is it typical at least 2 cycles taken for load from and store to a zero wait state accessible memory?
    Dear All, I expected load and store instructions accessing zero wait state accessible memory to take only 1 cycle (average and with pipeline filled), but it doesn't seem to. Is it typical even with...

    Greetings, I have a few questions regarding the Neoverse N1. According to the specifications, it mainly uses the ARMV8.2 ISA. However, there is possible support also for other instructions in other...
  • Minimum MMU table size on ARMv8 to map 4GB memory space, in AArch64 mode
    On ARMv7 Cortex-A8/9/7, to map 4GB memory space, the minimum MMU table size is 16 KB(section mapping). Any possible to map 4 GB memory space with 16 KB MMU table, on ARMv8, AArch64 mode?
