Program-Instruction-Controlled Instruction Flow Supervision |
摘要 |
A signature module calculates a signature during the execution of a program by a central processing unit based on program instructions to the central processing unit, and stores the signature in a signature register of the signature module. The signature module includes: a calculation unit configured to generate a signature value based on program instructions executed on the central processing unit; and an instruction information interface configured to receive at least one item of instruction information from the central processing unit which indicates whether an instruction currently being executed by the central processing unit was jumped to indirectly or directly. |
