Zusammenfassung: | PROBLEM TO BE SOLVED: To remarkably accelerate a comparison process and to reduce the number and circuit area of required active devices by removing one entire layer or level of logic at a comparator. SOLUTION: A dynamic data value B on a bus 12 is compared with a programmable reference value C. This system is provided with potential sources GND and VCC related to logically high and low reference values C, 1st lead 33 connected to a comparator 30, 2nd lead 13 connected to the bus 12 and 3rd leads 34 and 36 connected to the potential sources GND and VCC. Then, a programmable connection part connects the 1st lead 33, 2nd lead 13 and 3rd leads 34 and 36 so as to provide information concerning the relative levels of data value B on the bus 12 and reference value C by providing the dynamic data value B on the bus 12 and the potential sources GND and VCC to the comparator 30. |
