Abstract
A processor system having a processor core configured to control an external apparatus in accordance with a control algorithm; a signal acquisition managing device configured to receive state signals provided by the apparatus, perform corresponding actions, and generate corresponding synchronized command signals; and a peripheral module structured to receive the synchronized command signals and generate output signals to be processed by the processor core in accordance with the control algorithm.
Claims26
A processor system for use with an external apparatus, the system comprising:
- a processor core configured to control the external apparatus in accordance with a control algorithm;
- a signal acquisition managing device configured to receive state signals provided by the apparatus and to generate corresponding synchronized command signals which are synchronized relative to a control period;
- and
- a peripheral module structured to receive the synchronized command signals, to perform actions corresponding to command signals, and to generate output signals to be processed by the processor core in accordance with the control algorithm.
A signal acquisition managing device including:
- a plurality of input terminals structured to receive state signals;
- a trigger generation unit configured to build from the state signals a reference signal and generate event trigger signals, each representing a time in which an event has to be performed;
- and
- a scheduler unit structured to associate each event trigger signal with a synchronized command signal to be supplied towards an external peripheral module and representing the event to be performed.
A circuit for controlling an external apparatus, the circuit comprising:
- a signal acquisition managing device coupled to the external device to receive state signals from the external device, the signal acquisition managing device comprising:
- a trigger generator unit that receives the state signals and generates a reference signal and plurality of event trigger signals that each represent an event performance time.
