Abstract
Disclosed are a method and a system for controlling invoking of a hardware instruction. The method comprises: receiving a hardware instruction; determining whether the received hardware instruction is a legal instruction; and when it is determined that the received hardware instruction is a legal instruction, sending the hardware instruction to a corresponding hardware device. In this application, the legality of the hardware instruction is checked before the hardware instruction is sent to the hardware device, and only a legal hardware instruction can be sent to the hardware device for execution, thereby avoiding sending an illegal operation to the hardware device for execution, and improving the security of the hardware device.
