Design and Implementation of the MTX Operating System

Abstract

Chapter 7 covers memory management. It lists the goals of memory management and describes the various memory management schemes, which include variable-sized partitions, overlay, swapping, segmentation, paging and demand-paging based virtual memory. It also describes the process virtual address space in file-mapping and distributed shared memory systems. Then it describes memory management in the real mode MTX in detail. These include managing process images as variable-sized partitions, memory compaction and swapping. It also shows how to adjust the process heap size for dynamic memory allocation in user space.
