ABSTRACT:
A method of the data conversion, a data conversion circuit and a data conversion program are provided which make the memory capacity of the circuit for storing the converted data small and can make the error of the output data small. To comprise a priority encoder11outputting bit number of “1” located at the most significant bit in the input data as L data, a bit-extracting portion outputting (L-1) to (L-2) bits in the input data as N data and (L-3) to 0 bits as M data, a table address forming portion13outputting a first address obtained by combining the L data with the M data, a conversion-table storing portion14storing a conversion table where converted data corresponds to table addresses, a multiplexer15selecting 0 or converted data and a linear interpolation portion20processing interpolation based on the two converted data.
