Abstract
A processor which includes a fetch program counter circuit and an execute program counter circuit is disclosed. The fetch program counter circuit provides less significant program counter value bits in addition to a fetch program counter value. The execute program counter circuit generates an execute program counter value using the less significant program counter value bits. The execute program counter circuit receives a plurality of less significant program counter bit values and selects a single less significant program counter bit value thus generating execute program counter values in a multiple pipeline processor.
