Abstract
A data processing system having no system memory is disclosed. The data processing system includes multiple processing units. The processing units have volatile cache memories operating in a virtual address space that is greater than a real address space. The processing units and the respective volatile memories are coupled to a storage controller operating in a physical address space that is equal to the virtual address space. The processing units and the storage controller are coupled to a hard disk via an interconnect. The storage controller allows the mapping of a virtual address from one of the volatile cache memories to a physical disk address directed to a storage location within the hard disk without transitioning through a real address.
