Abstract
A multi-chip module includes a first die having a control processor to generate a signal to control an industrial process and an input/output interface. The multi-chip module also includes a second die having a supervisory processor and an input/output interface. A processor failure of one of the control processor and the supervisory processor is detected by the other of the control processor and the supervisory processor, and the processor that detects the failure is configured to assert a signal through its input/output interface to cause the industrial process to transition to a safe state in response to the failure. Additionally, the first and second dies are created using different process technologies.
Claims20
A multi-chip module, comprising:
- a first die comprising:
- a control processor to generate a signal to control an industrial process;
- and
- an input/output interface;
- a second die comprising:
- a supervisory processor;
- and
- an input/output interface;
- and
- wherein a processor failure of one of the control processor and the supervisory processor is detected by the other of the control processor and the supervisory processor, and the processor that detects the failure is configured to assert a signal through its input/output interface to cause the industrial process to transition to a safe state in response to the failure;
- and
- wherein the first and second dies are created using different process technologies.
A multi-chip module, comprising:
- a first die comprising:
- a control processor to generate a signal to control an industrial process;
- a supervisory processor;
- and
- an input/output interface;
- a second die comprising:
- an analog core supervisory processor configured to detect a failure of either the control processor or supervisory processor;
- and
- an input/output interface;
- and
- wherein the control processor is configured to detect a processor failure the supervisory processor or the analog core supervisory processor;
- wherein the supervisory processor is configured to detect a processor failure of the control processor or the analog core supervisory processor;
- wherein the processor or processors that detect the failure are configured to assert a signal through their input/output interface to cause the industrial process to transition to a safe state in response to the failure;
- and
- wherein the first and second dies are created using different process technologies.
A method for controlling an industrial process, comprising:
- generating a signal to control the industrial process;
- detecting, by a processor on a first die of a multi-chip module, a failure of a processor on a second die of the multi-chip module;
- and
- asserting, by the processor that detected the failure, a signal to cause the industrial process to transition to a safe state in response to detecting the failure;
- wherein the first and second dies are created using different process technologies.
