Abstract
A superscalar processing system that detects data hazards within instruction groups transmitted to the processing system utilizes a content-addressable memory, a plurality of pipelines, an instruction dispersal unit (IDU), and a control mechanism. The IDU receives an instruction group that includes a plurality of instructions and transmits the instructions of the instruction group to the plurality of pipelines. The control mechanism stores register identifiers of the instructions in the content-addressable memory and determines whether a register identifier of one of the instructions is stored in the content-addressable memory. When the register identifier of the one instruction is stored in the content-addressable memory, the control mechanism transmits a warning signal indicating that one of the instruction groups contained a data hazard.
