Abstract
There is provided a data processing apparatus, which is suitable for verifying memory systems. Processing circuitry issues a plurality of memory access requests to a plurality of addresses in a memory. Point-of-trust circuitry receives the memory access requests from the processing circuitry via a first set of intermediate circuits. Secure channel circuitry enables secure communication of a correspondence between the plurality of addresses from the processing circuitry to the point-of-trust circuitry. The point-of-trust circuitry determines whether the addresses in the memory of the memory access requests received via the first set of intermediate circuits have a predetermined relationship based on the correspondence.
