Abstract
A system for bus communication includes a first port coupled to a bus, comprising a first engine configured to respond to bus signals on the bus, according to a predetermined protocol. A second port couples to the bus, comprising a second engine configured to respond to bus signals according to the predetermined protocol. A control module couples to the second port and is configured to receive a port state signal, and to disable the second port based on the received port state signal.
Claims20
A system for bus communication, comprising:
- a first port coupled to a bus, the first port comprising a first engine configured to respond to bus signals on the bus, according to a predetermined protocol;
- a second port coupled to the bus, the second port comprising a second engine configured to respond to bus signals according to the predetermined protocol;
- and
- a control module coupled to the second port and configured to receive a port state signal, and to disable the second port in the event the received port state signal is a disable signal.
A method for improved bus communications, comprising:
- monitoring a bus, by a device coupled to the bus and comprising a first port and a second port, for bus traffic directed to the device;
- receiving, by the device, bus traffic directed to the device;
- in the event the received bus traffic is directed to the second port, receiving, by the device, a port state signal;
- in the event the received port state signal is a disable signal, disabling the second port;
- and
- in the event the received port state signal is an enable signal, processing the received bus traffic in accordance with a predetermined bus protocol.
An apparatus comprising a computer program product for improved bus communications, the computer program product having a tangible computer-readable medium with a computer program embodied thereon, the computer program comprising:
- computer code for monitoring a bus, by a device coupled to the bus and comprising a first port and a second port, for bus traffic directed to the device;
- computer code for receiving, by the device, bus traffic directed to the device bus;
- computer code for, in the event the received bus traffic is directed to the second port, receiving, by the device, a port state signal;
- computer code for, in the event the received port state signal is a disable signal, disabling the second port;
- and
- computer code for, in the event the received port state signal is an enable signal, processing the received bus traffic in accordance with a predetermined bus protocol.
