Abstract
The execution of time intensive instructions can lead to critical events being responded to late or not being responded to at all. An information processing apparatus comprises processing circuitry () for executing instructions comprising one or more time intensive instructions and exception generating circuitry () for generating at least one exception for the processing circuitry. The processing circuitry maintains a control value () for indicating whether or not the time intensive instructions can be executed. When a time intensive instruction is encountered, if the control value indicates that time intensive instructions cannot be executed then a first exception triggers the processing circuitry to suppress execution of the time intensive instruction. Alternatively, if the control value indicates that time intensive instructions can be executed, then the time intensive instruction is executed.
