DEVELOPMENT METHOD OF DATA PROCESSING SYSTEM

摘要

In development of a data processing system applying a semiconductor integrated circuit for data processing, comprising a non-volatile logical function block capable of being written electrically and a logical operation control block utilizing the logical function block as to execute the logic operation, data corresponding to required specification and function of the system is written in the logical function block. Thereby flexibility is obtained for setting and change of the required function for the semiconductor integrated circuit for data processing. The semiconductor integrated circuit for data processing also has an operation specification that the logical function block can be written by a writing device for a non-volatile semiconductor storage device capable of being written electrically. Thereby use convenience regarding the function setting of the semiconduc tor integrated circuit for data processing is improved.
