Abstract: Device for processing digital data and, more particularly, for reading out the maximum or minimum value of data belonging to a set of 2n codes in which a relation of order is established and in which each of said data has a rank R comprised between 0 and 2nnull1. The device includes a conversion circuit for each digital data to be processed, which circuit generates a transform which is a binary number composed of 2nnull1 binary elements Tnullxnull with xnull1 to 2nnull1Tnull2nnull1nullTnull2nnull2null . . . Tnullxnull . . . Tnull2nullTnull1nullin which T(x)null0 when x is strictly higher than R and T(x)null1 when x is lower or equal to R. The result of the conversions is received by circuits that carry out a digital processing thereof.
