Abstract:
A method for encoding/decoding digital data to be transmitted through a serial link, said digital data comprising a first data bit sequence and a second label bit sequence, said first and second sequences having first (m) and second (p) given bit lengths, said method comprising:an encoding phase comprising checking at least one slice of at least two consecutive bits, each of said slices being located in a predetermined area of said first bit sequence, so as to create a partitioning of the latter into parts of approximately equal length, said checking step including performing a test to determine whether the consecutive bits of each of said slices are in a same logical state, setting the bits of said second sequence to predetermined logical state configurations in one-to-one relation with a result of said test, and inverting at least one bit of said slices when the result of said test is positive and transmitting said first bit sequence without any modifications when the result of said test is negative.
