a$)(5)$ The ARM instruction MOVT$$ R$4,$ #$33$ replaces the leftmost $16$ bits of register R$4$ with the binary equivalent of the decimal constant $33$ and leaves the low $16$ bits unchanged. Show how this can be done on the MIPS processor for register $$4$ using at most three MIPS instructions. Each MIPS instruction should be a true$-$op instruction.

b$)(5)$ Show a single MIPS true$-$op instruction that uses MIPS registers and has the same effect on the MIPS processor as the following ARM instruction has on the ARM processor:

MOV R$15,$ R$14$
