Jump and Branch Instructions (Cont.)
j label         or         b label
Unconditionally jumps to a specified location.

beq rs, rt, label         # branch on equal
Branches to the specified label when the contents of rs equal the contents of rt, or it can branch when the contents of rs equal the immediate value.

bne rs, rt, label         # branch on not equal
Branches to the specified label when the contents of rs do not equal the contents of rt, or it can branch when the contents of rs do not equal the immediate value.

blt rs, rt, label         # branch on less
Branches to the label when the contents of rs are less than the contents of rt, or it can branch when the contents of rs are less than the immediate value. The comparison treats the comparands as signed 32-bit values.
