Claim 0:
1. A method for controlling access to an address space by a remap address space controller (RASC), the method comprising:
selectively remapping by the RASC a physical address of a transaction received from a bus master external to the RASC to form a remapped physical address according to a current execution context of the bus master, the selectively remapping being based on a determination of whether the current execution context of the bus master allows the transaction to access the address space, wherein determining whether the current execution context of the bus master allows the transaction to access the address space comprises: comparing by the RASC an access type of the transaction to access types which are allowed by the current execution context to the address space;
and selectively providing by the RASC the transaction with the remapped physical address to a memory bus based on the determination of whether the current execution context of the bus master allows the transaction to access the address space.
