ABSTRACT:
A FIR filter in a Gigabit transceiver in which data words are represented in three bits: SIGN representing word sign, SHIFT representing requirement for a shift operation, and ZERO indicating whether the word is zero. An AND gate ANDs an input coefficient and the ZERO bit, an XOR gate XORs the SIGN bit and the output of the AND gate, and a multiplier left-shifts the coefficient using the SHIFT bit and the output of the XOR gate. The circuit has a very low gate count.
