The mips architecture supports byte and halfword (16-bit) memory transfer operations. the instructions are load byte (ib), load byte unsigned (ibu), store byte (sb), load halfword (lh), load halfword unsigned (lhu) and store halfword (sh). code: short int a, bi //16-bit variables (a address 100) (b @ address 200) part a) assuming 16-bit operations are supported (lh, lhu, sh), write a mips code that swaps the variables a and b. part b) ifmips doesn't support byte and halfword operations, then we can access the memory using the load word' (lw) and 'store word' (sw) only, which are 32-bit operations. accordingly, rewrite the code above using only (iw, sw) to access the memory. you can use other logic/arithmetic/branch instructions.
