Abstract
An approach and mechanism for improving reliability, performance and on time execution of critical operations of a system, such as an HVAC. A controller may have two or more processing cores. One core may be dedicated to execution of critical operations of a system. Another core may be dedicated to less- or non-critical operations of the system. For instance, if there are delays relative to the less- or non-critical operations, these delays may be ineffective relative to the processing of critical operations.
Claims20
A multi-core processor comprising:
- at least two processor cores;
- and
- wherein:
- a first core of the at least two processor cores is dedicated to critical operations of a control system;
- a second core of the at least two processor cores is dedicated to non-critical operations of the control system;
- and
- the first core and the second core are connected to each other for exchanging data.
A method for utilizing a multi-core system, comprising:
- segregating two or more processor cores according to operations of a building component;
- and
- classifying the operations according to a need of an operation to be executed or commanded within a predetermined period of time;
- and
- wherein:
- the operations that need to be executed or commanded within a predetermined period of time are processed by a first processor core of the two or more processor cores;
- and
- the operations that lack a need to be executed or commanded within a predetermined period of time are processed by a second, another or other processor core or cores of the two or more processor cores.
A processing mechanism comprising:
- a first processor core;
- and
- a second processor core;
- and
- wherein:
- the first processor core is dedicated to critical operations of an HVAC system;
- the second processor core is dedicated to non-critical operations of the HVAC system;
- and
- the critical operations are processed by the first processor core within a predetermined period of time.
