Abstract
Application instructions for a sub-system processing unit are received through an application programming interface (API). The application instructions control a sub-system processing unit to process wireless messages directed to a main processing unit. A message rule may be generated based on the received application instructions and predefined conditions and actions stored in the sub-system processing unit. Responsive to receiving the wireless messages from sensors and/or tags external to the wireless terminal, an action may be performed at the sub-system processing unit according to the generated message rule to control and/or reduce processing of the wireless messages by the main processing unit.
Claims18
A computer-implemented method of controlling a sub-system processing unit of a wireless terminal that coordinates processing with a main processing unit of the wireless terminal, the method comprising:
- receiving application instructions for the sub-system processing unit through an application programming interface (API), wherein the application instructions control the sub-system processing unit to process wireless messages directed to the main processing unit;
- generating a message rule based on the received application instructions and predefined conditions and actions stored in the sub-system processing unit and based on an operating state of the main processing unit;
- and
- responsive to receiving the wireless messages from sensors and/or tags external to the wireless terminal, performing an action at the sub-system processing unit according to the generated message rule to reduce processing of the wireless messages by the main processing unit.
A wireless terminal component, comprising:
- a sub-system processor;
- a memory coupled to the sub-system processor and comprising computer readable program code embodied in the memory that when executed by the sub-system processor causes the sub-system processor to perform operations comprising:
- receiving application instructions through an application programming interface (API), wherein the application instructions control the sub-system processor to process wireless messages directed to a main processor of the wireless terminal;
- generating a message rule based on the received application instructions and predefined conditions and actions stored in the sub-system processor and based on an operating state of the main processing unit;
- and
- responsive to receiving wireless messages from sensors external to the wireless terminal, performing an action according to the generated message rule to control processing of the wireless messages by the main processing unit.
