Assignee: SILICONINTERVENTION INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A combinatorial circuit with feedback for producing an output that is the square root of an input, comprising:
a first combinatorial logic adder configured to receive two input values and to produce an output value that is the sum of the two input values to the first adder and is the output of the circuit, one of the inputs to the adder being an inverse of a circuit input;
a combinatorial circuit multiplier configured to receive two input values, each of the input values to the multiplier being feedback of the output of the circuit, and to produce an output value that is the product of the two input values to the multiplier and thereby a value that is a square of the output value; and
a second combinatorial logic adder configured to receive two input values and to produce an output value that is the sum of the two input values to the second adder, one of the inputs to the second adder being the output of the multiplier and the other input to the second adder being the output of the circuit, the output of the second adder being fed back as an input to the first adder;
thereby producing a circuit output that is the square root of the circuit input.
