Abstract
A method for memory protection in a multiprocessor system, involving receiving a request at a first carrier to perform a memory operation at a memory address, wherein the first carrier receives the request from a processor, determining by the first carrier whether the processor is permitted to access memory at the memory address using a carrier identification (ID) of a second carrier, wherein the second carrier is associated with a memory controller used to access the memory, and sending the request to the second carrier, if the processor is permitted to access the memory.
