Abstract:
1. An apparatus for detecting an operation value for input data comprising: a means for storing seed values corresponding to seed points determined according to a range of the input data and output data and an error rate; an address and data generator for comparing a predetermined reference value with the input data to generate an address of the storing means and revised input data corresponding to the input data; and an operator for performing a predetermined operation to output an operation value corresponding to the input data, using the seed values output from the storing means and the revised input data generated by the address and data generator, wherein the seed values stored in the storing means consist of values corresponding to unevenly spaced seed points, and wherein the address and data generator comprises: a comparison unit for comparing the predetermined reference values with the input data; an index generator for generating predetermined index information according to a comparison result output from the comparison unit; an address generator for generating addresses corresponding to the input data based on the index information output from the index generator; and a revised input data generator for generating said revised input data corresponding to the input data based on the index information output from the index generator.
