Parallel processing in human-machine interface applications

摘要

A human-machine interface (HMI) application (26) uses parallel processing. The HMI engineering system (24) allows explicit specification (44) of different cores of a multi-core processor (16) for different elements and/or actions. The programmer may design the HMI application for concurrent operation. The HMI engineering system (24) or runtime system (28) may test (56) for data dependency amongst the elements or actions and automatically assigns different cores where data is independent. During runtime, different threads for the HMI application (e.g., different elements and/or actions) are scheduled for different cores.

1. A system for parallel processing in a human-machine interface (HMI) application, the system comprising:
at least one actuator connection of an actuator of an industrial machinery; a multi-core processor electrically connected with the at least one actuator connection; a display operable to display HMI elements associated with the at least one actuator connection; an engineering system for creating the HMI application, the engineering system configured to allow user assignment of computer processing units of the multi-core processor based on selection by a user of different ones of the computer processing units of the multi-core processor for different ones of the HMI elements and to allow a setting by a user of actions for each of the HMI elements; a memory having stored the elements for the display and the actions corresponding to the elements together with the assigned computer processing units as an HMI application; wherein the multi-core processor is configured to associate a first sub-set of the actions with a first computer processing unit based on a first user selection, associate a second sub-set of the actions with a second computer processing unit based on a second user selection, schedule first and second HMI threads for the first and second computer processing units based on the first and second sub-sets, process the first and second HMI threads with the first and second computer processing units, and control the at least one actuator and the display of the elements as a function of the processing of the first and second HMI threads.
