Abstract
A method and apparatus for executing floating-point instruction pairs in a pipelined manner in which exceptions are predicted during an execution stage. In response to a possible exception, the execution pipeline can stall the pipeline. The floating-point pipeline and the integer pipelines are stalled in an execution stage and a decoding stage, respectively. Once stalled, the floating-point microinstructions are executed, the state of the machine is updated and then any exceptions are reported.
