ABSTRACT:
A method for approximating a base 2 logarithm of a binary input and the circuit to implement the method are disclosed. The circuit comprises means for determining the integer portion of the logarithm, a lookup table module, a residual function module, an adder module and a register. This circuit performs the approximation in one system clock cycle time.
