Processing data in an information handling system is disclosed that includes: in response to an event that triggers a flushing operation, calculate a finish ratio, wherein the finish ratio is a number of finished operations to a number of at least one of the group consisting of in-flight instructions, instructions pending in a processor pipeline, instructions issued to an issue queue, and instructions being processed in a processor execution unit; compare the calculated finish ratio to a threshold; and if the finish ratio is greater than the threshold, then do not perform the flushing operation. Also disclosed is moving the flush point.

A representative reconfigurable processing circuit and a reconfigurable arithmetic circuit are disclosed, each of which may include input reordering queues; a multiplier shifter and combiner network coupled to the input reordering queues; an accumulator circuit; and a control logic circuit, along with a processor and various interconnection networks. A representative reconfigurable arithmetic circuit has a plurality of operating modes, such as floating point and integer arithmetic modes, logical manipulation modes, Boolean logic, shift, rotate, conditional operations, and format conversion, and is configurable for a wide variety of multiplication modes. Dedicated routing connecting multiplier adder trees allows multiple reconfigurable arithmetic circuits to be reconfigurably combined, in pair or quad configurations, for larger adders, complex multiplies and general sum of products use, for example.
