Abstract (en)

[origin: WO9919795A1] Problems encountered during speculative execution of instructions are deferred. If the results of instructions that were speculatively executed are subsequently used, the integrity of the execution of the instructions is verified. If not, recovery code is executed that alters the state of the computer system (50) to create the appearance that the speculatively executed instructions had executed successfully.
