<P>PROBLEM TO BE SOLVED: To provide a logic development apparatus, which can secure CPU functions necessary for following logic, and improves reliable communications for I/O information and arithmetic processing capability of CPU. <P>SOLUTION: The logic development apparatus 20 for a built-in microcomputer 2 to be used in an ECU 1 is composed of a mother board 30 provided with application processing functions 31 and communication functions 30D, a core board 40, which has a pseudo microcomputer peripheral device 42, arithmetic functions 40M and communication functions 40D, and is connected with the mother board 30 through a PCI bus 39, and an IF board 50, which has hardware corresponding circuits 53 and 55 for the ECU 1, and is connected with the core board 40. Using the PCI bus 39, which is provided between the communication functions 30D for the mother board 30 and the pseudo microcomputer peripheral device 42 for the core board 40, data sending and receiving is directly performed between them. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
