You are given the following code. Note that floating-point instructions use floating point registers labeled f. Integer instructions use integer registers labeled x. loop: fld fld f0, 0(x1) f2, 0(x2) fadd f6, f2, f12 fsub f4, fo, f10 fmul f8,f4, f6 fsd f8, 0(x2) subi xl, x1, 8 subi x2, x2, 8 bnz x1, loop We are given the following latencies for the different types of instructions. Floating Point Add/Sub Load/Store Branch if taken 322 Floating point Multiply 5 Integer arithmetic Branch if not taken 1 Remember how to use latencies. For example, since fadd and fsub have latencies of 3, the fmul 8, 4, 6 which needs the results of fsub f4, fo, f10 must wait 3 cycles from when fsub starts. a). Show how many cycles are needed to complete one iteration without reordering, but with data forwarding. DO NOT use delayed branch. Create a table that includes stalls (not pipeline stages but stalls between instructions). b). Reorder instructions and show how many cycles are needed to complete one iteration. Show reordered code and cycles needed. c). Unroll the loop 2 times, reorder instructions and show how many cycles are needed to complete two iterations
