Methods and circuits for generating parallel pseudorandom binary sequences

摘要

A method for generating M parallel pseudorandom binary sequences (PRBSs), each comprising a 2ⁿ−1 sequence of pseudorandom bits, includes loading into the circuit an initial M-bit word, the initial M-bit word comprising M sequential bits selected from a pre-determined PRBS-n sequence, wherein n1 and Mn. The method includes generating, using a plurality of logic gates of the circuit, a next M-bit word using at least n+1 of the M sequential bits of the initial M-bit word. The method includes repeatedly generating, using the logic gates of the circuit, the next M-bit word from a previous M-bit word using the at least n+1 of M sequential bits of the previous M-bit word, resulting in M parallel sequences of the PRBS-n sequence. The method includes transmitting the generated next M-bit words on an M-bit wide parallel bus.
