PROBLEM TO BE SOLVED: To unnecessitate a manual capacitance check by discriminating the arithmetic processing capacitance of programming gate array(PGA) through an information processor and selecting either the array or the processor for executing operation. SOLUTION: A ROM 20 stores a program for executing function operation through a PGA 40, program for executing the same function operation through a CPU, and program for selecting any one of these programs. Besides, a RAM 30 is provided with a table showing the block of PGA 40 at a position to be used. When an instruction for replying the remaining capacitance of prescribed function is received, while referring to this table, a CPU 10 acquires the remaining capacitance of PGA 40. Next, the CPU 10 automatically discriminates whether or not the PGA 40 can provide the capacitance required for executing the prescribed function and at the time of positive discrimination, the PGA 40 executes that function operation but in case of negative discrimination, that function operation is executed on the side of CPU 10. |
