ABSTRACT:
A new virtual memory system is disclosed having a virtual address space including a gap of inaccessible virtual addresses within the virtual address space. A new virtual memory allocation routine is disclosed providing a starting address of accessible virtual addresses allocated to a currently executing process in a response to a request. The accessible virtual addresses are virtually contiguous, and include no addresses from within the gap of inaccessible virtual addresses. A new virtual memory deallocation routine is further disclosed providing deallocation of ranges of virtual addresses which may or may not include addresses within the inaccessible gap.
