Abstract
A processing system includes a hardware address protection for limiting access to communication system addresses based on a virtual machine ID (VMID), a plurality of processing cores, a volatile memory, a hardware secure module (HSM), and a further communication system connecting the HSM to the communication system. A slave interface circuit of the further communication system receives a write request from the communication system and transmits the VMID in the write request to the HSM. The HSM accesses virtual machine configuration data to determine address data indicating positions of first and second memory areas in the volatile memory, and sends, via a master interface circuit, read/write requests, including the VMID, to the communication system to read command data from the first memory area and write response data to the second memory area. The HSM then stores a response notification to a register of the further communication system.
