Step 1
The `lw` (load word) instruction in MIPS assembly language has the format `lw rt, offset(base)`, where `rt` is the destination register, `offset` is the immediate value added to the base address in the register `base`. Show more…

What will be the effective address and operand to be loaded by using Register indirect mode? (A) 200,400 (B) 400,1000 (C) 400,500 (D) 200,1000
Computer Organization and Architecture
Machine Instructions, Addressing Modes
The two word instruction is stored in memory at an address designated by symbol $W .$ The address field of the instruction (stored at $W+1$ ) is designated by the symbol $Y$. The operand used during the execution of the instruction is stored at address symbolized by $Z$. An index register contains the value $X$. State how $Z$ is calculated from the other addresses if the addressing mode of the instruction is (A) Direct (1) $Z=\operatorname{Mem}(Y)$ (B) Indirect (2) $\quad Z=Y+W+2$ (C) Relative (3) $Z=Y+X$ (D) Indexed (4) $\quad Z=Y$ (A) $\mathrm{A}-4, \mathrm{~B}-1, \mathrm{C}-2, \mathrm{D}-3$ (B) $\mathrm{A}-3, \mathrm{~B}-1, \mathrm{C}-2, \mathrm{D}-4$ (C) $\mathrm{A}-4, \mathrm{~B}-2, \mathrm{C}-1, \mathrm{D}-3$ (D) $\mathrm{A}-3, \mathrm{~B}-2, \mathrm{C}-1, \mathrm{D}-4$
Consider a hypothetical processor with an instruction of type LW $R_{1}, 40\left(R_{2}\right)\left(R_{3}\right)$. Which during execution reads a 16 -bit word from memory and stores it in a 16 -bit register $R_{1} .$ The effective address of the memory location is obtained by the addition of constant 40 , contents of $R_{2}$ and $R_{3}$ registers. Which of the following best reflects the addressing mode implemented by this instruction for the operand in memory? (A) Immediate addressing (B) Register addressing (C) Register indirect scaled addressing (D) Base with index and displacement addressing
