4. Write the MIPS minimal sequence of instructions for the following C statement: G = x[i]+x[i+1]+x[i+2]+a; Assume that "i" is in register $s1, "G" is in register $s2, "a" is in register $s3 and the base address of the array x is in $s4. 5. Some computers have explicit instructions to extract an arbitrary field from a 32-bit register and to place it in the least significant bits of a register. The figure below shows the desired operation: 31 31 O... field 31-j bits j-i bits 32-(-i) bits i+1 bits 0000 field J-/bits Find the shortest sequence of MIPS instructions that extract a field for the constant values i=5 and j=22 from register $t0 and places it in register St3. 4.
