A method for managing communications involving a lockstep processing comprising at least a first processor and a second processor can include receiving, at a data synchronizer, a first signal from a first device. The method can also include receiving, at the data synchronizer, a second signal from a second device. In addition, the method can include determining, by the data synchronizer, whether the first signal is equal to the second signal. When the first signal is equal to the second signal, the method can include transmitting, by the data synchronizer, the first signal to the first processor and the second signal to the second processor. Specifically, in example embodiments, transmitting the first signal to the first processor can occur synchronously with transmitting the second signal to the second processor.

Methods for managing communications involving a lockstep processing system

Contextual awareness associated with resources can be employed to facilitate controlling access to resources of a system, including function blocks. A resource manager component (RMC) can pre-load a defined number of respective versions of configuration parameter data associated with respective applications in each resource. With regard to each application, the RMC can associate a context value, unique for each application, with the respective versions of configuration parameter data associated with that application. When a current application is being changed to a next application, the RMC can write the context value associated with the next application to a context select component (CSC). Each resource can read the context value in the CSC, identify and retrieve the version of configuration parameter data associated with the next application based on the context value, and configure the function block based on the version of configuration parameter data.

Contextual awareness associated with resources

A method of providing high integrity communication in a high integrity processing system having at least two redundant application processors in a non-lockstep configuration where the redundant application processors are running the same application and where the redundant application processors are connected to at least one input/output processor by a communication channel.

Method of providing high integrity processing

A system and method for controlling processor instruction execution. In one example, a method for synchronizing a number of instructions performed by processors includes instructing a first processor to iteratively execute instructions via a first set of iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the first set of iterations is less than a number of instructions executed in a prior iteration of the first set of iterations. The method also includes instructing a second processor to iteratively execute instructions via a second set of iterations until the predetermined time period has elapsed. A number of instructions executed in each iteration of the second set of iterations is less than a number of instructions executed in a prior iteration of the second set of iterations. The method includes determining whether additional instructions are to be executed.

A system and method for controlling processor instruction execution. In one example, a method for controlling a total number of instructions executed by a processor includes instructing the processor to iteratively execute instructions via multiple iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the iterations is less than a number of instructions executed in a prior iteration of the iterations. The method also includes determining the total number of instructions executed during the predetermined time period.

Controlling total number of instructions executed to a desired number after iterations of monitoring for successively less number of instructions until a predetermined time period elapse

A unit monitors power and reports to a central location. The unit receives an A/C power signal to be monitored, senses a zero crossing of the A/C power signal, and delays an interval so as to sample the A/C signal after a 90 degree phase delay after the zero crossing. Samples are stored in a static recording medium, such as an EEPROM. A processor detects anomalous conditions in the A/C signal using stored configuration values, and reports to a central location at a unit-dependant time after detecting an anomaly. The unit responds to commands from the central location and reports the recorded samples of the A/C power signal, as well as a contemporaneous value of the A/C power signal. The unit also receives and updates revised configuration values.
