Abstract
A method and apparatus for performing a fast jump address calculation is disclosed. A field from the instruction is provided to an adder, on the assumption that it is the displacement value, without actually determining whether it is a displacement value. A fixed instruction length is also provided to the adder, on the assumption that the instruction will have that length. Finally, the current instruction address bits from the program counter are provided to the adder. These are added together to provide a jump address.
