Consider the following MIPS code segment. Note: values of a0 and a1 are eassed from the calling function and the result is returned in v0. f1: lw \$te, ($a) addi $t1,$0,1 loop: bge $t1,$a1, exit mul \$t2, \$t1, 4 add $t2,$t2,$a0 lw \$t2, 0 (\$t2) ble $ t2, $ to, next add $t0,$t2,$0 next: addi $t1,$t1,1 j loop exit: add $v0,$t0,$0 jr $ra a) Translate the function fl into a C code [use variable names as register names]. b) Describe briefly what the function fl perform
