Translate the following MIPS pseudo instructions into real MIPS instructions. That is, show the mapping of the pseudo instructions to MIPS instructions. Note that the only register you can use as temporary is register $at ($1). (the meaning of the symbol || is that the order of the operations does not change the result of the operations.

1. ble Rs, Rt Label

Branch on less than or equal;

If (Rs <= Rt) then branch to label

2. abs Rd, Rs

Absolute;

Rd = absolute-value (Rs)

3. slei Rd, Rs, Constant

Set less than or equal immediate;

If(Rs <= Constant) then Rd = 1, else Rd = 0.

4. bgeo Rs, Label

Branch on greater than or equal to one;

If(Rs >= 1) then branch to label

5. swapr Rs, Rt

Swaps the contents of registers Rs and Rt

Rs <-- Rt || Rt <-- Rs

6. swapm (Rs), (Rt)

Swaps the contents of the memory locations pointed to by registers Rs and Rt

M[Rs] <-- M[Rt] || M[Rt] <-- M[Rs]
