PURPOSE:To improve debugging efficiency, by constituting a system so that only a changed part can be corrected when changing a program. CONSTITUTION:A storing circuit which is capable of executing write, read-out and correction of write inputted from the outside is constituted of a random access memory (RAM)1. A host computer system 2 connected to the RAM1 is provided with a microcomputer, an RAM, an ROM, a paper tape reader keyboard display part, etc., so that write and read-out to the RAM1 can be executed. The host computer system 2 and a debug CPU4 are switched by a switching controlling circuit 3, and are connected to the RAM1. |
