ABSTRACT:
A signal processor includes a normalization circuit (101, 102, 103, 106, 107, 108) for input data and a conversion table (110). A higher digit portion of mantissa portion after normalization is logarithmically converted by looking up table data stored in the conversion table (110). By shifting a decimal point position of the converted data, exponent data can be used as integer data and added to the converted data so that the conversion process is achieved.
