Patent ID: 8526294

Claim:
A method for transmitting messages from first units of an integrated circuit to at least one second unit of the integrated circuit, the method comprising: transforming first digital messages by the first units into second digital messages; adding the second messages of the units; and transmitting said added second messages to said at least one second unit, wherein the transformation of the first messages into second messages comprises applying an orthogonal transformation by means of vectors obtained from rows or columns of an identity matrix, and wherein a bit (bi) of a first message of rank i is transformed into an n-bit word (Mi) of a second message of rank i by the steps of: a) transforming said bit of the first message of rank i into an intermediary n-bit word (mi) by application of a vector obtained from a row or a column of an identity matrix of rank n; and b) obtaining the n-bit word of the second message of rank i by replacing the bit of rank i of said intermediary word with value “0”.
