Reliability enhancement systems and methods

A method of reliability enhancement, said method comprising:

• performing an instruction parsing process, comprising determining a functionality associated with program instructions;
• executing the program instructions and incident to executing the program instructions performing fault checking, wherein the fault checking comprises:
• speculatively executing multiple sets of operations contemporaneously, wherein the multiple sets of operations are functional duplicates of the program instructions;
• and
• comparing results from the speculative execution;
• and
• performing error mitigation based on a mismatch result from the comparison.

A method of executing a program, said method comprising:

• converting said program comprising instructions of a high level language into a plurality of instructions that are native to a processor, said plurality of instructions for execution on said processor, wherein a portion of said program is converted into a first code portion of native machine instructions and a second code portion of native machine instructions;
• wherein said first code portion and said second code portion are functionally equivalent to each other and functionality equivalent to said portion of said program;
• said processor speculatively executing said first code portion and said second code portion to generate respective first results and second results;
• comparing said first results against said second results to produce a comparison result;
• and
• performing an error mitigation process responsive to a mismatch within said comparison result.
