Patent ID: 7412618

Claim:
A method of de-skewing a plurality of data bits transmitted over an elastic interface bus comprising the steps of: encoding an IAP training pattern with a first data bit, wherein the step of encoding results in a scrambled pattern, wherein the first data bit is one of the plurality of data bits; transmitting the scrambled pattern from a driver to a receiver, wherein the step of transmitting a scrambled pattern results in a transmitted scrambled pattern; transmitting a first clock signal from the driver to the receiver; receiving the transmitted scrambled pattern at the receiver, resulting in a received scrambled pattern, wherein the received scrambled pattern comprises a plurality of data eyes; receiving the first clock signal at the receiver, resulting in a received first clock signal, wherein the received first clock signal comprises a plurality of clock edges; delaying the received scrambled pattern by less than a bit time to align centers of the plurality of data eyes with a plurality of nearest of the plurality of clock edges; and decoding the scrambled pattern using the IAP training pattern, wherein the step of decoding results in a decoded training pattern and a decoded data bit; wherein the IAP pattern has a plurality of attributes including: a number X of beats; a plurality of isolated ‘1’s; a plurality of isolated ‘0’s; a plurality of instances in which consecutive beats in the IAP pattern equal 01010; one instance of a timing pattern; and combining the values of every Nth data beat equals a recognizable pattern, wherein the recognizable pattern includes a single 1 and a plurality of ‘0’s.
