Abstract
A method and apparatus for executing conditional branch instructions by a data processing system containing a programmable microprocessor and multiple VLSI gate arrays connected by a bi-directional bus, whereby a branch condition is obtained from a storage location resident on a VLSI gate array executing asynchronous and external to the microprocessor. The branch condition is fetched and evaluated in parallel with the fetching of the branch target address and the incrementing of the program counter. The microprocessor changes instruction sequence control depending on the results of the branch condition evaluation.
