Question
Q6 (20%) Some RISC-V assembly instructions are shown below. Assume that the variables
f,g are assigned to registers x5, x6, respectively. Assume that the base address of the
arrays A and B are in registers x10 and x11, respectively.
slli x30, x5, 2 // x30 = f*4
add x30, х10, х30 // x30
slli x31, x6, 2 // x31
&A[f]
g* 4
&B[g]
add x31, х11, х31 // x31 %3D
lw x5, 0 (x30) // x5 =
addi x12, х30, 4
A[f]
lw x30, 0 (x12)
add x30, х30, х5
sw x30, 0 (x31)
1. What's the meaning of the last four instructions.
2. What is corresponding C statement?
