1. [12 points] This problem uses the RISC-V program fragment below. addi x12, x0, 5 add x11, x0, x0 add x19, x0, x0 addi x20, x0, 150 x110 // x19= LI : bge x11, x12, Exit s11 x13, x11, 3 add x14, x16, x13 ld x15, 0(x14) blt x15, x20, L2 sd x0, 0(x14) add x19, x15, x19 beq x0, x0, L3 //x16 = address of array[0] L2 : addi x15, x15, 1 sd x15, 0(x14) addi x11, x11, 1 jal x L1 Exit: (a) Write code (C or Java) that performs the same function as this code. (b) Assume that array[] = { 100, 150, 200, 250, 300), what is the value of x19 at the end? (c) Assume that array[] {100, 150, 200, 250, 300), what is the average CPI of the code frag- ment, assuming the cycle latencies shown in the table below? format R-type -type S-type SB-type U-type UJ ype CPI 4 (d) Rewrite the assembly code above to use pointers instead of array indexes. Your code should modify x16 to do this, and you should have no need for x14
