Method for finding starting bit of reference frames for an alternating-parity reference channel

摘要

The present invention discloses a method for locating the reference frames of the reference lane on the transmitting data bus. The present invention addresses this object by disclosing a method whereby the relationship between the size of the reference frame transmitted over the reference lane and the width of the data bus is such that the reference frame is bit-shifted automatically until it is aligned with the data bus.

主权项

1. A method of receiving data over a data bus, the method comprising:
identifying a fixed position of a plurality of fixed positions in relation to the data bus within each consecutive m bits received on a reference channel, wherein the identified fixed position is aligned with the data bus; determining whether a starting symbol of a reference frame of a plurality of reference frames received on the reference channel is located at the identified fixed position, wherein the starting symbol of each reference frame of the plurality of reference frames shifts in position in relation to the data bus; in response to determining that the starting symbol of the reference frame is located at the identified fixed position, locking the position of the reference frame; and in response to determining that the starting symbol of the reference frame is not located at the identified fixed position, shifting the position of the reference frame by a symbol differential, wherein the symbol differential is based on a relationship between a size of the reference frame and a width of the data bus.
