TAILIEUCHUNG - Lecture Operating systems: A concept-based approach (2/e): Chapter 5 - Dhananjay M. Dhamdhere

Chapter 5 - Memory management. This chapter is devoted to the fundamentals of memory management. It begins by discussing how memory protection is implemented in the hardware by using special registers in the CPU. It then discusses how efficient use of memory is achieved by reusing memory released by a process while handling subsequent memory requests, and how techniques for fast memory allocation and deallocation may cause memory fragmentation. | PROPRIETARY MATERIAL. © 2007 The McGraw-Hill Companies, Inc.

Managing the memory hierarchy The memory hierarchy is comprised of several memory units with different speeds and cost Efficient operation of a process and the system depends on effective use of the memory hierarchy Efficient operation of a process depends on hit ratios in faster memories of the hierarchy, ., the cache and memory Efficient operation of the system requires many processes to be present in memory Managing the memory hierarchy How different levels in the hierarchy are managed L1 cache and L2 cache Allocation and use
