Abstract
Systems, apparatuses, and methods for pre-computing early age indicators for a non-shifting reservation station. A reservation station may include a plurality of entries storing a plurality of instruction operations prior to issuance to an execution unit. The reservation station may include control logic for pre-computing early age indicators for specifying which entry of each adjacent pair of entries is the oldest ready instruction operation. The early age indicators may be routed through registers and then through additional levels of control logic for determining the oldest ready instruction operation in all of the entries of the reservation station.
