处理器管理的主要任务是对处理器进行分配,并对其运行进行有效的控制和管理。存储器的管理主要是指内存分配、内存保护、地址映射和内存扩充等。内存分配是为每个程序分配内存空间,提高存储器的利用率,允许正在运行的程序申请附加的内存空间,以适应程序和数据动态增长的需要。有两种内存分配方式:即静态分配和动态分配,二者的区别在于程序运行期间能否允许再重新申请新的内存空间。内存保护的意义是确保每个程序都在自己的内存空间中运行,互 The main task of processor management is to allocate the processor and control its operation effectively. Memory management mainly refers to memory allocation, memory protection, address mapping and memory expansion. Memory allocation is allocated for each program memory space, improve memory utilization, allowing running applications for additional memory space to meet the dynamic growth of programs and data needs. There are two kinds of memory allocation: static allocation and dynamic allocation, the difference between the two is that the program can run during the re-apply for a new memory space. The significance of memory protection is to ensure that each program runs in its own memory space, and vice versa
