APPARATUS AND METHOD FOR GENERATING MEAN VALUE

摘要

There is provided an apparatus for generating a mean value of N-bit input data in M-bit operations (M and N are integers, and M is greater than N) by dividing a total sum of the input data by number of times the data are input, including a ROM (Read Only Memory) storing therein, as denominators, quotients of dividing 2<SUP>M-N</SUP> by integers in a range from one to a maximum allowable number of times for data input. Further, ROM addresses of the denominators are determined based on the integers.
