Abstract
Methods and apparatuses of compensating for delays of a storage device are disclosed. The method includes: performing a communication operation a preset number of times with the storage device through the extension line, each time if a correct response is received from the storage device, recording a status value of the current communication operation as a first value, otherwise recording as a second value, to obtain a resultant data string; searching, in the resultant data string, for a longest data segment comprised of the continuous first values; taking a delay value of the communication operation corresponding to the status value at the middle position of the longest data segment as an optimal delay value; and setting the optimal delay value as a phase difference between a source clock and a sampling clock of the storage device to compensate for the delays caused by the extension line of the storage device.
