Abstract
A memory protection unit including hardware logic. The hardware logic receives a transaction from a virtual central processing unit (CPU) directed at a bus slave, the transaction being associated with a virtual CPU identification (ID), wherein the virtual CPU is implemented on a physical CPU. The hardware logic also determines whether to grant or deny access to the bus slave based on the virtual CPU ID. The virtual CPU ID is different than an ID of the physical CPU on which the virtual CPU is implemented.
