ARM 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 We will learn ARM assembly programming at the Instruction set defines the operations that can Auto-indexing addressing (LDR R0, [R1, #4]!). As described by an ARM instruction reference, LDR and STR are basic instructions for moving data in and out of processor. LDR(Load register) :- move data LDR instructions load a register with a value from memory. STR instructions store a register value into memory. The memory address to load from or store to The ARM instruction set formats are shown below. Figure 4-1: ARM instruction set formats LDR. Load register from memory.
