Abstract
A microprocessor includes a register and a comparator. The register stores an address area, the address area requiring a guarantee of an access order. The comparator compares an address of the address area held in said register with an address of an address area indicated in an access request from CPU, and outputs a signal to execute an access request succeeding the access request from the CPU after executing an access request preceding the access request from the CPU when the address area indicated in the access request from the CPU matches the address area held in said register.
