Zusammenfassung:The invention discloses an access control method and device, a computer readable storage medium and electronic equipment. The method comprises the steps that an address conversion request is generated through a target virtual machine, and the address conversion request comprises an intermediate physical address; converting the intermediate physical address into a physical address through a memory management unit; determining access permission information of the target virtual machine to the physical address through the virtualization manager; and in response to the access permission information representing that the target virtual machine has the access permission to the physical address, configuring the physical address in the direct memory access controller through the target virtual machine. According to the embodiment of the invention, the manufacturing cost of the chip can be reduced. 公开了一种访问控制方法、装置、计算机可读存储介质及电子设备。其中,该方法包括:通过目标虚拟机生成地址转换请求,地址转换请求包括中间物理地址;通过内存管理单元将中间物理地址转换为物理地址;通过虚拟化管理器确定目标虚拟机对物理地址的访问权限信息;
