Abstract
A programmable logic circuit (100) includes a processor element (101) having: a logic cell (300) which can modify the function according to first setting information and generates data by performing a predetermined logic calculation on an input signal; a cross connect switch (301) for generating data by performing alignment, copying, and inversion of the data from the logic calculation means according to second setting information; and a memory control unit (201) which reads out the first or the second setting information from a memory device (102) according to branch setting information and supplies it to the logic calculation means and the data processing means for performing control. According to the first and the second setting information successively read from the memory device (102), each of unit logic circuits successively modifies a part or whole of the logic cell (300) and the cross connect switch (301) and performs a predetermined sequence circuit operation.
