A computer processor, a computer system and a corresponding method involve a reservation station that stores instructions which are not ready for execution. The reservation station includes a storage area that is divided into bundles of entries. Each bundle is switchable between an open state in which instructions can be written into the bundle and a closed state in which instructions cannot be written into the bundle. A controller selects which bundles are open based on occupancy levels of the bundles.
