Abstract
PURPOSE: To secure the use of the bus structure limited physically through the logical multiplication by using the multi-value logic circuit for the signal line for memory driving.
CONSTITUTION: Main memory 1 is shared by arithmetic control unit 2 and input/ output device 3, and mixer 5, bus line 4 and slicer 6 are provided between unit 2 and device 3. Mixer 5 converts the supplied parallel and binary digital information into one multi-value signal which is transferred to slicer 6 through bus line 4. Slicer 6 returns the multi-value signal to the original binary digital information and then applies the information to memory block control unit 7. As a result, the simultaneous and parallel access can be given to the different blocks of main memory 1 from unit 2 and device 3.
