Chapter s Operating System 5.1.1 Resource allocation and related functions Memory sharing Like the CPU, the memory also cannot be shared concurrently. However, unlike the CPU, its availability can be increased by treating different parts of memory as different resources. Both the partitioning and the pool-based allocation approaches can be used to manage the memory resource. Memory preemption can also be used to increase the availability of memory to programs. Special terms are used for different memory preemption techniques, hence the term memory preemption" is rarely used in our discussions. 存储器共享 和CPU一样,存储器也不能并行共享。但与CPU不同的是,可以把存储器 的不同部份看作不同的资源,因此可以增加它的可用性。资源分区和基于 资源池的分配方式都适用于存储器资源管理。存储器抢占也可用于提高程 序对存储器的可用性,但由于对不同的存储器抢占技术都有专用术语,故 在本书很少使用“存储器抢占”的说法。 水《第和英语 5-19Chapter 5 Operating System 计算机专业英语 5-19 Memory sharing Like the CPU, the memory also cannot be shared concurrently.
