Speculative execution did not appear overnight. It emerged gradually from techniques that loosened strict sequential execution. In 1967, Robert Tomasulo’s work on the IBM System/360 Model 91 introduced dynamic scheduling and register renaming, allowing instructions to execute out of order without violating program semantics. Around the same time, James Thornton’s scoreboard in the CDC 6600 kept pipelines active in the presence of hazards. These mechanisms did not speculate—but they removed structural barriers that once forced processors to stall. Once out-of-order execution became viable, speculation became irresistible.
