CONSTITUTABLE LOGICAL ELEMENT

摘要

PURPOSE: To improve the flexibility of a constructible logical element by making every constructible logical block produce an output signal at its output in response to the input signal of its input and also to the program data. CONSTITUTION: A constructible logical block 2500 includes a combination function/control generator 2501 to receive the inputs from the buses 2502-1 to 2502-4. The generator 2501 communicates with four output ports 2503-1 to 2503-4 which can be constructed independently of each other. These output ports are connected to the generator 2501 via the buses 2504-1 to 2504-4 to receive the signals from the generator 2501 and also supply the feedback signals to the generator 2501. Every output port supplies plural output signals via each of output buses 2505-1 to 2505-4. As a result, the high flexibility and high logical capability are secured for a constructible logical element.
