Abstract
A method for the monitoring of transmissions in a transmission branch of a bidirectional interface, which besides the transmission branch has a reception branch standing in connection with the transmission branch, has the steps a) sending out of information by means of the transmission branch, and b) evaluation of defined characteristics of the sent information via the reception branch of the same interface, whereby preferably depending on the evaluation of the sent information a setting of parameters of the transmission branch is effected, so that future information is sent out with use of these parameters.
Claims22
Method for operating a bidirectional interface, the method comprising:
- monitoring transmissions in a transmission branch of a bidirectional interface comprising a transmission branch and a reception branch connected to the transmission branch;
- sending information by means of the transmission branch;
- evaluating defined characteristics of the sent information via the reception branch of the same interface;
- and
- setting parameters of the transmission branch as a function of the sent parameters dependent upon the result of the evaluation, so that future information is sent out with use of these parameters.
Method for operating a bidirectional interface, the method comprising:
- monitoring the temporal bit lengths in a transmission branch of a bidirectional digital interface comprising a transmission branch and a reception branch connected to the transmission branch;
- sending digital information by means of the transmission branch,
- evaluating temporal bit lengths of the sent information via the reception branch of the same interface;
- and
- in the event that the evaluated temporal bit lengths, over a defined time period, deviate from a desired value by more than a permitted tolerance, effecting a correction of the bit length in the transmission branch.
A controller for a bidirectional interface, the controller comprising a processor and a computer-readable storage medium having computer-executable instructions for execution on the processor and for implementing a method for operating a bidirectional interface, the computer-executable instructions comprising instructions for:
- monitoring transmissions in a transmission branch of a bidirectional interface comprising a transmission branch and a reception branch connected to the transmission branch;
- sending information by means of the transmission branch;
- evaluating defined characteristics of the sent information via the reception branch of the same interface;
- and
- setting parameters of the transmission branch as a function of the sent parameters dependent upon the result of the evaluation, so that future information is sent out with use of these parameters.
Bidirectional interface, comprising:
- a transmission branch for transmitting signals via a bus,
- a reception branch for receiving signals from the bus, wherein the reception branch is connected to the transmission branch in such a way that signals transmitted by the transmission branch can also be read via the reception branch, and
- a control unit, which evaluates, via the reception branch, signals transmitted via the transmission branch in order to control defined properties of these signals, wherein the control unit is configured to set parameters of the transmission branch dependent upon the result of the evaluation.
Bidirectional digital interface comprising:
- a transmission branch for sending signals via a bus,
- a reception branch for receiving signals from the bus, wherein the reception branch is so connected with the transmission branch that signals sent by the transmission branch are read via the reception branch, and
- a control unit which evaluates the temporal bit length of signals sent out via the transmission branch and read via the reception branch and, depending on the result of the evaluation, sets by software the bit length of the transmission branch if the evaluation shows, over a defined time period, a deviation from a desired value beyond a permitted tolerance.
A controller for a bidirectional interface, the controller comprising a processor and a computer-readable storage medium having computer-executable instructions for execution on the processor and for implementing a method for operating a bidirectional interface, the computer-executable instructions comprising instructions for:
- monitoring the temporal bit lengths in a transmission branch of a bidirectional digital interface comprising a transmission branch and a reception branch connected to the transmission branch;
- sending digital information by means of the transmission branch, and
- evaluating temporal bit lengths of the sent information via the reception branch of the same interface;
- and
- in the event that the evaluated temporal bit lengths, over a defined time period, deviate from a desired value by more than a permitted tolerance, effecting a correction of the bit length in the transmission branch.
