Transcendental function evaluation

A circuit, comprising:

• an input coupled to a first register, wherein the first register stores an input operand having a mantissa, wherein the mantissa includes a set of most significant bits (MSBs) and a set of least significant bits (LSBs);
• a first sub-circuit having a first sub-circuit input coupled to the input and a first sub-circuit output, wherein the first sub-circuit input is configured to receive the input operand and determine a linear term based on the input operand;
• a second sub-circuit having a second sub-circuit input coupled to the input and a second sub-circuit output, wherein the second sub-circuit input is configured to receive the input operand and determine a quadratic term based on the input operand;
• a third sub-circuit coupled to the first sub-circuit output and the second sub-circuit output and configured to receive the linear term, the quadratic term and determine a constant term based on the linear term and the quadratic term, the third sub-circuit generating an output operand based on the linear term, the quadratic term, and the constant term;
• an output coupled to a second register, wherein the second register stores the output operand.
