SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE AND CIRCUIT EVALUATION SYSTEM

PROBLEM TO BE SOLVED: To easily evaluate a function at a high speed without mounting a semiconductor integrated circuit used for image processing of an image forming apparatus or the like on the image forming apparatus and without increasing the number of pins on the semiconductor integrated circuit and nets on a substrate. SOLUTION: This semiconductor integrated circuit A1 comprises: a first input side selector for selectively outputting either of image data to be input to a first input terminal or a second input terminal to a first image processing means; a second input side selector for selectively outputting either of the image data to be input to the first input terminal or the second input terminal to a second image processing means; a first output side selector for selectively outputting either of image data from the first image processing means or the second image processing means to a first output terminal; a second output side selector for selectively outputting either the image data from the first image processing means or the second image processing means to a second output terminal; and a control means 10 for controlling the respective selectors.
