ERROR MANAGEMENT

摘要

An electronic device is described which receives data from a transmitting device via a communications channel. The electronic device comprises digital processing circuitry arranged to process the data received via the communications channel to generate output data, error detection circuitry arranged to detect errors in the output data, and monitoring circuitry arranged to monitor the quality of digital processing conducted by the digital processing circuitry and generate digital performance data indicative of the monitored quality of digital processing. The electronic device also comprises control circuitry responsive to error information comprising errors detected by the error detection circuitry and the performance data generated by the monitoring circuitry to modify the operation of one or both of the transmitting device and the electronic device. The digital performance data provides the control circuitry with additional information for use in identifying where errors in signal processing are arising, enabling an informed decision be made to modify the operation of either the transmitting device or receiving device in some way, either to reduce the occurrence of errors in the output signal or to improve the speed and/or efficiency of the transmitter and/or receiver.
