Abstract
Increase the effective data rate of high-speed data communication. It has a memory unit, a reception signal line, and a transmission signal line capable of communicating with an external device via a control circuit and an equalizer, controllers for controlling transmission and reception of signals to and from the external device, and a correction coefficient associated with an identification information and the identification information of the external device. The control circuit sets the correction coefficient associated with the identification information to the equalizer.
Claims10
A communication system communicating with an external device via transmission signal lines and reception signal lines, the communication system comprising:
- a memory unit that stores identification information of the external device and a correction coefficient associated with the identification information;
- an equalizer that operates based on the correction coefficient;
- and
- a control unit that sets the correction coefficient stored in the memory unit to the equalizer.
A control device comprising a circuit configured to:
- receive identification information from an external device by performing an authentication process;
- search a correction coefficient associated with the identification information;
- and
- set the correction coefficient.
A method for an equalizer to adjust received signals, the method comprising:
- searching identification information of an external device coupled to the equalizer and a correction coefficient associated with the identification information;
- setting the correction coefficient associated with the identification information of the external device to the equalizer;
- and
- selecting a correction coefficient by 1) receiving test signals based on the set correction coefficient, and 2) repeatedly changing the correction coefficient of the equalizer.
