Question
Decide the addressing mode based on the given semantics (for the ARM ISA): ldr r 1, [r0,#4] (1 Point) base-indexbase-offsetregister indirectnone of the above
Solution 1
The addressing mode for the given semantics (ldr r1, [r0,#4]) in ARM ISA is base-offset. This is because the instruction is loading a value into register r1 from the memory address calculated by adding the immediate value 4 to the contents of the base register r0.
Solution 2
The addressing mode for the given semantics (ldr r1, [r0,#4]) in ARM ISA is base-offset. This is because the instruction is loading a value into register r1 from the memory address calculated by adding the immediate value 4 to the contents of the base register r0.
