Abstract
A hierarchal organization of registers containing error indicators is utilized to determine which of a plurality of error recovery modules is to be executed. A redundancy mask and a priority mask stored in a data table associated with each register are sequentially applied to each register in order to eliminate redundant error indicators resulting from a common fault and to set the order of execution of error recovery modules. Thus, the redundancy and priorities associated with detected errors can be controlled substantially independent of the actual error recovery actions to be taken.
