Abstract
A computer implemented method searches a unified translation lookaside buffer. Responsive to a request to access the unified translation lookaside buffer, a first order code within a first entry of a search priority configuration register is identified. A unified translation lookaside buffer is then searched according to the first order code for a hashed page entry. If the hashed page entry is not found when searching a unified translation lookaside buffer according to the first order code, a second order code is identified within a second entry of the search priority configuration register. The unified translation lookaside buffer is then searched according to the second order code for the hashed page entry.
