Abstract
At an instruction pipeline of a data processor, pipeline resource conflicts are detected by setting, for each executing instruction, one or more assignment indicators to indicate which pipeline resources are to be utilized for executing the instruction. The instruction pipeline detects a pipeline resource conflict if an instruction is assigned a pipeline resource for which the assignment indicator is set. In addition, for selected pipeline resources, such as registers in a register file, the instruction pipeline can detect a pipeline resource conflict if more than one instruction attempts to access the pipeline resource when the assignment indicator for the resource is set. In response to detecting a pipeline resource conflict, the instruction pipeline is flushed and returned to a checkpointed state, thereby protecting the instruction pipeline from architectural state errors.
