Abstract
Devices, methods and systems are provided for processing measurement data. An exemplary device includes a first module to provide data and an interrupt, a control module coupled to the first module to obtain the data from the first module and provide an indication after obtaining the data, and an interrupt control module coupled to the first module and the control module to notify the first module to clear the interrupt in response to the indication from the control module.
Claims20
A device comprising:
- a first module to provide data and an interrupt;
- a data control module coupled to the first module to obtain the data from the first module and provide an indication after obtaining the data;
- and
- an interrupt control module coupled to the first module and the data control module to notify the first module to clear the interrupt in response to the indication from the data control module.
A method of processing measurement data, the measurement data being based at least in part on output from a sensing arrangement, the method comprising:
- determining, by an interrupt control module, whether the measurement data associated with an interrupt generated by a first module has been serviced by a data control module;
- and
- notifying, by the interrupt control module, the first module to clear the interrupt in response to determining the interrupt has been serviced.
A signal processing system comprising:
- a plurality of sensing arrangements to provide measurement data indicative of a respective characteristic sensed by a respective sensing arrangement;
- and
- a processing device comprising:
- a plurality of filtering modules, each filtering module of the plurality of filtering modules being coupled to a respective sensing arrangement of the plurality of sensing arrangements to generate an interrupt and a filtered measurement value associated with the interrupt based at least in part on the respective measurement data from the respective sensing arrangement;
- a data control module coupled to the plurality of filtering modules to obtain filtered measurement values from the plurality of filtering modules and provide indications after obtaining the filtered measurement values;
- and
- an interrupt control module coupled to the plurality of filtering modules and the data control module to notify the respective filtering modules to clear the respective interrupts in response to the indications from the data control module.
