ELECTRONIC DEVICE AND ADDRESS ACCESS METHOD

The present application relates to the technical field of electronics, and provides an electronic device and an address access method, for use in ensuring the accuracy of memory block authentication, improving the reliability of security isolation, and improving the performance of electronic devices. The electronic device comprises a hardware module and an IOMMU module corresponding to the hardware module. The IOMMU module comprises a filter register, and the filter register stores at least one authentication page tag number, which is used for indicating the page tag number of a memory page to which the hardware module has access operation permission. The IOMMU module is used for: obtaining a target physical address corresponding to a target virtual address and the page tag number of a target memory page, wherein the target virtual address is a virtual address in a section of virtual addresses corresponding to the target memory page to be accessed by the hardware module; and determining whether the at least o
