VERFAHREN UND EINRICHTUNG ZUR STEUERUNG EINES ZUGRIFFS AUF PERIPHERIEGERÄTE |
摘要 |
The unit has a register (21) for obtaining an access authorization code (Code-AA) to allow access to a peripheral (P). A hardwired logic (22) compares the code with a preset reference value (Code-UMCA) calculated by a generation unit (24). A latch (23) generates and delivers an electric validation signal (SIGVAL) of an access request signal (CS-RQ) to a logic combination unit (25), when the code and the reference value are equal. Independent claims are also included for the following: (A) a processor having an access control hardware unit (B) a method of controlling an access to a peripheral (C) a computer program having an instruction to perform a method of controlling an access to the peripheral (D) utilization of an access control hardware unit for validating an access signal to a peripheral. |
