WebbThe AArch64 processor provides two major modes of operation, referred to as execution states. They are 32-bit AArch32 state, and 64-bit AArch64 state. Both of these execution states provide privileged modes and a user mode. The AArch32 execution state allows the processor to execute code written for the ARMv7 and older processors. clinching press https://deckshowpigs.com
