Nettet11. sep. 2013 · In the latest version of the Arm architecture, Armv7, two new instructions were introduced to improve the situation: movw, or move wide, will move a 16-bit constant into a register, implicitly zeroing the top 16 bits of the target register. NettetARM uses a load-store model for memory access which means that only load/store (LDR and STR) instructions can access memory. While on x86 most instructions are allowed to directly operate on data in memory, on ARM data must be moved from memory into registers before being operated on.
