Manner and the device whose run security in order to run the multiple functions where criticality differs depending upon the single processor is high

摘要

(57) Abstract Manner of this invention being the manner which makes multiple functions the processor run (70) whose memory of the program (81) and the data (82) and access to the input-output register (77) are possible, the function which it should run allocated access right respectively, split the addressable point field into the addressable point multiple partitions and allocated functional access right, split operating time of the processor into multiple cyclic time partitions and allocated functional access right, at each time new time partition is started, verifying whether or not the processor ended the run of function immediately before,Doing, if it starts the functional task which corresponds, while the processor (70) is access the addressable point partition, it compares the access right which is granted to the addressable point partition which is accessed with the access right which is granted to present time partition (111) (113) and the result of comparison has not shown consistency, you send the error signal.
