Time triple modular redundancy, also known as TTMR, is a
patented single-event upset mitigation technique that detects and corrects errors in a computer or microprocessor. TTMR allows the use of
very long instruction word (
VLIW) style microprocessors in space or other applications where external sources, such as radiation, would cause an elevated rate of errors. TTMR permits
triple modular redundancy
Triple is used in several contexts to mean "threefold" or a " treble":
Sports
* Triple (baseball), a three-base hit
* A basketball three-point field goal
* A figure skating jump with three rotations
* In bowling terms, three strikes in a row
* I ...
