Abstract (en)
[origin: WO2021254598A1] The present disclosure relates to a requesting entity configured to request access to a range of virtual addresses and to a memory arrangement configured to allocate physical memory to the range of virtual addresses and to make the requested virtual addresses available to the requesting entity. Embodiments thereof enable to request multiple pages over a single range, which minimizes the number of requests and hence allows for reduced the request queue size. As the number of request messages significantly decreases, embodiments of the present invention also minimize communication volume between the requesting entity and the memory arrangement. Furthermore, embodiments of the invention allow for multiple responses for the same request, wherein each response refers to a subrange of the range of virtual addresses requested. This enables the requesting entity to immediately start DMA to parts of the translated addresses and the memory arrangement to translate a range of memory pages.
