Patent ID: 7876747

Claim:
A line selection unit for selecting one of a plurality of lines carrying data from a first unit to a second unit, individual lines being selectable by the decoding of a n-bit selection number, the unit comprising; (A) at least one addressable table containing m table locations, each of which is indexed by an address number and contains an n-bit selection number, wherein m is substantially greater than an amount of different n-bit selection numbers, such that a particular n-bit selection number is contained in a plurality of different ones of the m table locations of the at least one table; (B) a random, or pseudo-random, number generator that generates an address number in response to an input and applies the address number to the at least one table for selection of one of the m table locations in the table, thereby providing as an output the n-bit selection number contained in the selected table location; and (C) means for decoding the n-bit selection number of the output to select one of said lines corresponding to the content of the selected table location therein.
