Patent ID: 7881363

Claim:
A data transmission rate adjustment apparatus applied to a data receiving terminal, and said data transmission rate adjustment apparatus comprising: a driving module, for performing a predetermined calculation based on a request with an information of desired transmission rate to generate a divisor; and a control module, for dividing a reference frequency by said divisor to generate a first transmission rate so that said data receiving terminal can receive data sent from a data sending terminal through said driving module with said first transmission rate; wherein said driving module monitors a transmission error rate of said received data and adjusts said divisor if said transmission error rate exceeds a predetermined value, and said control module generates a second transmission rate based on said adjusted divisor, and said data receiving terminal receives data through said driving module with said second transmission rate; wherein said control module further comprises a status register for storing an operating status of said control module, and said driving module monitors said transmission error rate by checking the data stored in said status register.
