Abstract
In various examples, a system comprises a computing device comprising a transmitter coupled to a high frequency serial communication interface. The transmitter may transmit a signal to another computing device via the high frequency communication interface. The system comprises a processor coupled to the high frequency serial communication interface. The processor may: generate a lower frequency protocol signal, a value of the lower frequency protocol signal to cause the another computing device to perform a management operation, and transmit the lower frequency protocol signal on the high frequency serial communication interface.
Claims20
A non-transitory machine-readable storage medium encoded with instructions, the instructions that, when executed, cause a processor of a computing device to:
- receive, via a communication interface of the computing device, a signal comprising data encoded with a high frequency serial communication protocol and data encoded with a serial communication protocol that has a lower frequency than the high frequency serial communication protocol,
- filter, with a capacitor, the received signal into a high frequency protocol signal and a lower frequency serial protocol signal;
- read a value of the high frequency signal;
- and
- read a value the lower frequency protocol signal.
A method comprising:
- receiving, via a communication interface of a computing device, a signal comprising data encoded with a high frequency serial communication protocol and data encoded with a serial communication protocol that has a lower frequency than the high frequency serial communication protocol,
- filtering, with a capacitor, the received signal into a high frequency protocol signal and a lower frequency serial protocol signal;
- reading, with a first processor, a value of the high frequency signal;
- reading, with a second processor, a value the lower frequency protocol signal;
- and
- responsive to reading the value of the lower frequency signal, performing a management operation on the computing device.
A system comprising:
- a computing device, the computing device comprising:
- a transmitter coupled to a high frequency serial communication interface, the transmitter to transmit a signal to another computing device via the high frequency communication interface;
- a processor coupled to the high frequency serial communication interface, the processor to:
- generate a lower frequency protocol signal, a value of the lower frequency protocol signal to cause the another computing device to perform a management operation;
- and
- transmit the lower frequency protocol signal on the high frequency serial communication interface;
- a capacitor network to:
- soften edges from the lower frequency protocol signal;
- and
- add the softened lower frequency protocol signal to the high frequency protocol signal on the high frequency communication interface.
