| 摘要 |
A circuit for a data processing apparatus is disclosed, said circuit comprising a data input operable to receive digital signal values, said circuit comprising: spurious signal detection logic operable to monitor a digital signal value within said circuit, and determine at least one of: a safe time window during which it is expected that said digital signal values input into said circuit may cause data transitions in said monitored digital signal value and a transition time window in which it is expected a data transition will occur; and in response to detecting either a data transition in said monitored digital signal value outside of said at least one safe time window or no data transition in said transition window, said spurious signal detection logic is operable to output a detection signal.
