Abstract

Instructions within a processor are managed by receiving, at a recovery unit of the processor, an instruction that modifies a control register residing within the recovery unit. The recovery unit receives a first set of data associated with the instruction from a general register. A second set of data associated with the instruction is retrieved from the control register by the recovery unit. The recovery unit performs at least one binary logic operation on the first set of data and the second data.
