摘要: Methods and apparatus to efficiently detect faults are described. In an embodiment, an encoded value may be generated based on a portion of an instruction address and a portion of a corresponding result value. The encoded value may be used to determine whether an entry corresponding to the encoded value is absent from a screening storage unit. Other embodiments are also described.
