Other AbstractThe utility model relates to a universal field bus receiver of a ternary-content addressable memory, which comprises a sampling point generating circuit, a polarity correcting circuit, a shift register, a counting control circuit and a programmable state machine, wherein the input of the sampling point generating circuit is connected with a bit synchronism circuit the polarity correcting circuit outputs polarity information to the shift register the input of the shift register is connected with the polarity correcting circuit and the shift register outputs to a register the input of the counting control circuit is connected with the sampling point generating circuit and the counting control circuit outputs to a sequential control circuit the programmable state machine comprises a ternary-content addressable memory array which is connected with a time schedule controller and is connected to a double-port RAM array through a priority processing circuit the double-port RAM array outputs to a status register and an output register that outputs to the counting control circuit, the bit synchronism circuit, the polarity correcting circuit and the sampling point generating circuit. The universal field bus receiver has excellent universality, can replace various existing field bus receiving circuits, and can also be used in other communication protocols which use a Manchester code in a physical layer.
