An apparatus and method for floating point exception prediction and recovery. In one embodiment, a processor may include instruction fetch logic configured to issue a first instruction from one of a plurality of threads and to successively issue a second instruction from another one of the plurality of threads. The processor may also include floating-point arithmetic logic configured to execute a floating-point instruction issued by the instruction fetch logic from a given one of the plurality of threads, and further configured to determine whether the floating-point instruction generates an exception, and may further include exception prediction logic configured to predict whether the floating-point instruction will generate the exception, where the prediction occurs before the floating-point arithmetic logic determines whether the floating-point instruction generates the exception.
