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?
In ARM7 and ARM9 PC=current + 8, but in the cortex-A7(8-stage pipeline) the PC is also the same value(PC=current +8), how does this work?

I think the cortex-A7 has 8-stage pipeline, the PC value is also current+8(this is back-forward for old design), but…

High efficiency, midrange or high performance Cortex-A - What is the difference?
A question that I am asked many times is – what is the fundamental difference between the high efficiency, mid range and the high performance application processors in the ARM Cortex family?
The simple answer to this is – the power budget…
