ABSTRACT:
A floating point unit comprising: 1) an execution pipeline comprising a plurality of execution stages for executing floating point operations in a series of sequential steps; and 2) a try-again reservation station for storing a plurality of instructions to be loaded into the execution pipeline. Detection of a denormal result in the execution pipeline causes the execution pipeline to store the denormal result in a register array associated with the floating point unit and causes the execution pipeline to store a denormal result instruction in the try-again reservation station. The try-again reservation station subsequently re-loads the denormal result instruction into the execution pipeline and the de-normal result instruction retrieves the denormal result from the register array for additional processing.
