example

[0089] The improvement of the performance of the embedded Linux system by the LKTL thread library is tested, and the response time of the embedded Linux system is evaluated when the LKTL thread library is not used and when the LKTL thread library is used. The test environment uses the simulation environment of the virtual machine, and the following three tests are carried out:

[0090] (1) Creation delay when creating 10 and 100 threads respectively;

[0091] (2) The response delay when the system calls open and close of the file system are executed 1000 times;

[0092] (3) Execution delay of a typical client application in C / S mode, the client and the server perform simple information interaction.

[0093] Through the simulation experiment, the following test results are obtained:

[0094]

[0095]

[0096]

[0097]

[0098] Experimental results show that this method can significantly improve the performance of embedded Linux applicat...

Abstract

The invention relates to a method for realizing kernel level process lib based on embedded Linux operating system, which realizes an integral kernel process manage system, provides kernel process management, signal amount management, memory management and log management, and AIP function interface of the function subgroup of standard C lib. The invention has the advantages that 1, the invention can modify little on kernel to support the software real-time or hardware real-time calling mechanism of prior embedded Linux operating system and confirm the application real-time demand, 2, the invention can completely eliminate the consumption of repeated switch of application process between user state and kernel state, to improve the integral performance of embedded Linux application system, 3,the invention shields the complexity of kernel module programming, to provide a development frame for developers and a series of programming interfaces (API), thereby reducing development and application complexity and improving development efficiency.

Description

technical field [0001] The invention relates to the field of embedded operating systems, in particular to a method for realizing a kernel-level thread library based on an embedded Linux operating system. Background technique [0002] The kernel is the inner core of the operating system, and other parts of the system must rely on the services provided by the kernel, such as managing hardware devices, allocating system resources, and so on. The operating system kernel is usually composed of an interrupt service program that responds to interrupts, a processor scheduler that manages multiple processes, a memory management program that manages process address spaces, and system services such as network and inter-process communication. [0003] As an operating system based on the GNU specification, Linux is increasingly popular due to its diversity of hardware support, high efficiency and stability of kernel operation, flexibility of application development, unique on-demand tail...
