DYNAMIC RECONSTITUTION SYSTEM OF PROGRAM GATE ARRAY

摘要

PROBLEM TO BE SOLVED: To obtain a programmable array provided with a dynamically reconfigurable function. SOLUTION: A programming array, including plural programming words is installed in each of plural logic cells 19 of a programmable gate array(PGA) 13. Each programming word is capable of being linked with control structure of the logic cells. The programming words are selectively linked and as a result, the plural functions are executed by the logic cells 19 in the PGA 13. As a result, the PGA 13 having many virtual logic cells which are more than the number of actual physical logic cells is provided. Therefore, the PGA 13 with more logic cells 19 than those physically provided with the PGA 13 can be emulated by the PGA 13.
