3. (15 pts.) Consider the following fragment of C code: for (i=0; i<=100; i=i+1) a [i] = b[i] + c; Assume that a and b are arrays of words and that the base address of a is in $a0 and the base address of b is in $a1. Register $t0 is associated with variable I and register $50 with the value of c. You may also assume that any address constants you need are available to be loaded from memory. (1) (10 pts.) Write the code for MIPS. (2) (5 pts.) How many instructions are executed during the running of this code if there are no array out-of-bounds exceptions thrown? (3) How many memory data references will be made during execution?
