Abstract
A method for processing noise interference in a serial AT Attachment (SATA) interface. In the method, when a receiver does not receive a SOF primitive (start of frame primitive) but does receive an EOF primitive (end of frame primitive) or WTRM primitive (wait for frame termination primitive), the receiver outputs a R_ERR primitive (reception error primitive) to enable a transmitter to resend original data and thus to eliminate the interference. In addition, if the transmitter detects an error during the data transmission, a HOLD primitive (hold data transmission primitive) will be issued to temporarily stop the data transmission.
Claims2
A method for processing noise interference in a data accessing device with a SATA (Serial Advanced Technology Attachment) interface, the method comprising the steps of:
- enabling a receiver to output a R_RDY primitive (receiver data ready primitive) after the receiver has received a X_RDY primitive (transmission data ready primitive);
- enabling the receiver to output a R_ERR primitive (reception error primitive) when the receiver has detected a EOF primitive (end of frame primitive) before the receiver has detected a SOF primitive (start of frame primitive);
- and
- enabling the receiver to receive data after the SOF primitive is detected.
