Bit finder circuit

Bit finder circuit for finding the first bit 0/1 in an m-bit input word from a start bit onwards and in a predetermined direction, the positions of said bits in said m-bit word being defined by an n-bit code, characterized in that it includes a crosspoint matrix of m rows and n columns, each crosspoint including a change-over contact means (ABC), with a make contact means (AB) and a break contact means (AC), and another make contact means (AD) all contact means having a common terminal (A) the rows of change-over contact means (ABC) being controlled by respective bits of said m-bit word and the break contact means (AC) of the change-over contact means (ABC) of each row being coupled to respective bits of the n-bit code identifying the bit of the m-bit word controlling these break contact means, and in that the make contact means (AB) of the change-over contact means (ABC) of a same column are connected in series, whilst said other make contact means (AD) of a same column are connected in parallel to a same output terminal (IA, IB), the rows of said other make contact means being controlled by a single-row selection circuit (TR).
