SIGNAL AUTO-TUNING SYSTEM AND METHOD OF USING THE SAME

摘要

A signal auto-tuning system is provided, which comprises a host, a controller, an expander, and a storage unit, The expander comprises a first error counting unit, a second error counting unit, an error-count temporary table, an error-count evaluating unit, and an adjusting unit. The expander receives/transmits a first signal with relation to the controller, and the expander receives/transmits a second signal with relation to the storage unit. The adjusting unit determines whether to adjust either of the first signal and the second signal, based on a result determined by the error-count evaluating unit.

1. A signal auto-tuning system, comprising:
a host; a controller configured to receive/transmit a signal with relation to the host; an expander configured to connect with the controller and to receive/transmit a first signal with relation to the controller; and at least one storage unit configured to store data and to receive/transmit at least one second signal with relation to the expander, wherein the expander comprises a first error counting unit, at least one second error counting unit, an error-count temporary table, an error-count evaluating unit, and an adjusting unit, the first error counting unit is configured to count a first retransmission count of the first signal for a first interval, the at least one second error counting unit is configured to count at least one second retransmission count of the at least one second signal for a second interval, the error-count temporary table is configured to respectively store the first retransmission count and the at least one second retransmission count, the error-count evaluating unit is configured to respectively determine whether the first retransmission count and the at least one second retransmission count is abnormal or not, and the adjusting unit is configured to determine whether to adjust the first signal and the at least one second signal, based on a result determined by the error-count evaluating unit.
