ABSTRACT:
A pipelined data processor capable of automatically storing in an external memory all essential information relating to the internal state thereof upon the detection of an access fault during instruction execution. Upon correction of the cause of the fault, the data processor automatically retrieves the stored state information and restores the state thereof in accordance with the retrieved state information. The data processor then resumes execution of the instruction. The faulted access may be selectively rerun upon the resumption of instruction execution. In response to detecting a particular sequence of a loopable instruction followed by a conditional branch instruction which selectively branches back to the loopable instruction, the data processor enters a loop mode wherein the loopable instruction and the branch instruction are internally recirculated around the pipeline to save instruction fetch cycles.
