Abstract
A method and apparatus for high speed decoding of a 20 bit wide data into 16-bit wide data in which the first ten bits and the lower ten bits are decoded simultaneously to ensure complete decoding and where the decoding of the second ten bits is dependent upon the running disparity of the first ten bits, the second ten bits are decoded twice, one assuming the decoded first ten bits will have a positive running disparity, and a second time assuming that the decoded first ten bits will have a negative running disparity.
