Abstract

PURPOSE:To greatly decrease the number of storage elements which are capable of reading and writing, and to realize a small-sized control device simulation system, by providing a correction address storage part, a correction data storage part and an access control part. CONSTITUTION:In case when there is no correction to an ROM, a correction existence discriminating flag 9 of a correction address storage part 6 is cleared, an output gate 10 and 11 are closed and opened, respectively, and a regular access is executed. Subsequently, when an address to be corrected is accessed by an address and an access control signal, the correction existence discriminating flag which has been read out shows that there is an address to be corrected, a readout control signal 3 becomes high potential, and the output gate 10 and the output gate 11 are opened and closed, respectively. On the other hand, a correction data address which has been read out is sent to a correction data storage part, and reads out a correction data. In this way, an old control data is not read out, and the correction data is sent out to a control data signal line 5.
