Abstract: A method of memory allocation in a host computer includes: allocating one or more regions of physical working memory for use by an application, the regions individually including contiguous physical memory segments, but the regions not necessarily being contiguous between themselves; generating a segment address table having at least as many entries as the total number of physical memory segments allocated to the application; populating entries of the segment address table sequentially and contiguously with the physical addresses of the physical memory segments across the or each region in order; presenting to the application a contiguous virtual addressable space having at least as many virtual memory segments as the total number of physical memory segments allocated to the application; and mapping from virtual memory addresses to physical memory addresses by reference to the segment address table.
