1. A system for developing the logic to be implemented in a built-in microcomputer that is used while being incorporated in an electric control unit, comprising:

  • a center block including at least a first central processing unit that deals with the logic, a first memory in which data including a program in which the logic is implemented is stored, a first interface via which said center block communicates with the outside, and a first internal bus over which said first central processing unit, said first memory, and said first interface are interconnected;

    a peripheral block including at least quasi microcomputer peripheral devices that simulate, by software, the peripheral devices of a microcomputer, a second interface via which said peripheral block communicates with the outside, and a second internal bus over which said quasi microcomputer peripheral devices and said second interface are interconnected; and

    an internal bus over which said center block and peripheral block are interconnected, wherein;

    said center block, said peripheral block, and said interface bus are substituted for said built-in microcomputer in order to implement the logic.
