, with multi-level indexes and integrated indexes. Multi-level index: UNIX three-level index structure: Access a file: file name-> file directory-> FCB-> Disk Improve file system performance: Disk scheduling: when multiple disk access requests are waiting, adjust the service sequence of these requests according to certain policies. Reduces the average disk service time, which is fair and efficient. Disk scheduling algorithm: 3. to execute the hell

Features of the operating system:From the point of view of resource management--five basic functions1. Process and thread management --process thread state, control, synchronous mutex, communication scheduling, etc.2. Storage Management--allocation/recycling, address translation, storage protection, etc.3. File Management--file directory, file operation, disk space, file access control4. Equipment Management--equipment drive, allocation and recovery,

and task 22 tasks. When you create a task, you define task 1 with a priority higher than task 2. So the system performs task 1 first. After Task 1 executes 3S, a message is sent to Task 2, Task 1 hangs, Task 2 begins execution, Task 2 executes 1S, a message is sent to Task 1, Task 2 hangs, Task 1 begins execution, and so on. The system task scheduling flowchart is shown in 3. After running, see the 6713 D

Implement a simple Embedded Operating System (1) Implement an embedded operating system that can't do anything1. First determine the CPU. Here we use embedded CPU for simplicity, such as the arm series. The reason why we use a short Instruction Set)The convenience of a type of CPU is that there is no disti
