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.

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.
