•  Content Experiments
  • Lab1：Bootloader/Interrupt/Device Driver
    • Bootloader starts the operating system
    • The state before the operating system starts and do the preparatory work
    • Running the operating system hardware support
    • How the operating system is loaded into memory
    • Two types of interrupts: peripheral interrupt, the interrupt trap

• • Lab2: Physical Memory Management
    • Understanding x86 segmentation / paging mode, to understand how the operating system manages the physical memory space of continuous

 

• • Lab3: Virtual Memory Management
    • Understand the mechanisms and swapped out page table (swap) mechanism
    • Outages, a page fault processing, memory page replacement algorithm based

 

• •  Lab4: kernel thread management
    
    • How to use the CPU efficiently complete the work
    • Creating relatively user process simpler kernel mode thread
    • Dynamic management of kernel threads

 

• •  Lab5: User Process Management
    
    • User mode process to create, execute, switching and dynamic management process end
    • User mode kernel service calls to get through the system kernel-mode process

 

• •  Lab6: the process of scheduling
    
    • Understand the operating system and scheduling process scheduling algorithm

 

• • Lab7: synchronization mutex
    
    • How interprocess exchange and sharing of information
    • Specific synchronization and mutual exclusion of the impact on system performance
    • The reason Deadlock, how to avoid
    • Philosopher food problem

  

•  Lab8: File System
