AbstractA CPU executes program instructions which result in valid and invalid intermediate results. By selecting the desired intermediate results, a program is able to be successfully executed. Analysis of the intermediate results must avoid plausible wrong results. A programmable feature allows the instruction decoder to provide plural answers, including plausible wrong answers. Instruction output selection logic selects a predetermined buffer, and this permits further microprocessor operation with the correct intermediate result.
