Abstract

PURPOSE:To prevent the occurrence of invalid access by temporarily storing interrupt type data from an interrupt controller and discriminating whether the access of a shared resource from a CPU is valid or not and reporting chip selection and the invalid access. CONSTITUTION:Interrupt type data from an interrupt controller 5 is temporarily stored in an interrupt type storage means 7. An access validity/invalidity discriminating means 61 discriminates whether the access to a shared resource 10 is valid or not based on interrupt type data stored in the means 7 and the address signal and the access mode signal from a microprocessor CPU 1. When the means 61 discriminates that this access is invalid, a chip select control means 63 invalidates the chip select signal to the resource 10 and an invalid access reporting means 62 reports the occurrence of invalid access to the CPU 1. Thus, the occurrence of invalid access is prevented in advance.
