Abstract
A CPUhaving a processorand an internal data cacheIS operated in combination with a dummy interfacewhich simulates the existence of an external memoryhaving the same address space as the cache memorybut which does not store data written to it. In this way, a conventional CPU can be operated without read/write access to an external memory in respect of at least part of its memory address space, and therefore with a higher performance resulting from faster memory access and reduced external memory requirements. The CPUmay be one of a set of CPU chipsin a data processing system, one or more of those chipsoptionally having read/write access to an external memory
