The previous article introduced the Starting Process of the resource shortage embedded system, and now introduces the Starting Process of the resource extensiveness embedded system. Generally, memory-wide and rich operating systems are plug-in with SDRAM, And the CPU computing power is relatively strong, such as SoC based on core such as cortex A and MIPS 74k. Is the difference between the two

A simple understanding of C language Embedded Assembly, Embedded Assembly Recently I have looked at the implementation of the spin lock. The main implementation of the loop lock of the self-selected lock is similar to the following. This implementation uses an Embedded Assembly (from the sanos kernel, the source code has two implementations, there is no problem w

This paper introduces the start-up process of resource-scarce embedded system, and introduces the startup process of resource-rich embedded system now.Memory resource-rich operating system is generally plug SDRAM, and CPU computing power is stronger, such as based on Cortex A, MIPS 74k and other core Soc.Is the difference between two types of embedded system arch

Due to hardware restrictions in embedded systems, the huge and bloated X Windows in Embedded Linux systems are not suitable. We need a high-performance, lightweight GUI system. Generally, the GUI suitable for Embedded Linux systems has the following features: 2. It is small in size and occupies less flash and ram. When installing the GUI system, you should be abl

Embedded Linux and 51/430/stm32 Embedded development of the Difference and Association summary: Microcontroller series: 8051, MSP 430, STM32 f0-3 (ARM cortext m0-m3 series), etc.The main feature is that there is no memory management unit, no Linux operating system with virtual memory, only bare-metal programs or a Ucos class of real-time operating systems can be run. The main work is peripheral driver devel

Embedded flash player on web page (1), embedded flash The recent project involves the use of Flash players. Videos need to be played on webpages, and different video resources need different players, based on the Stability of use, the complexity of embedding, and the performance advantages and disadvantages, the two embedding methods (different players) are summarized, and the supported video resources are

Cross-origin calling of Embedded Web browser pages: Embedded Web browser pages My problems: The JS method on worker can be called normally.

My previous question stopped for a long time because-I went to write a book.ObjectiveI started working in March 2012 and now I'm six years away. For the past six years, I have never known anything about SQL Server, only the simplest C # programmers have started, stepping back from a nameless outsourcing company to the middle of a larger financial institution, with wages rising to nearly four times times the size of a new job. In the process of struggle, I also go a lot of detours, once very depr

System Disk (SD) includes the operating system, driver, middleware, application and font library, UI resources, and other files. This article describes the file system design of the SD area. The primary goal of a file system is to locate and read/write a single file. Generally, the Code cannot be modified by itself, that is, no write operation is performed after mass production. The SD File System of the embedded system is designed to locate a file an

You guys, I want to implement this function! My website has a page embedded in the Baidu page. then, I search for keywords on the Baidu page, go to the Baidu result page, and click a website on the result page, pop-up website (note that a new page is displayed here), how can my website obtain the url address of this pop-up page, or is there a better solution!

Q: Why does my Embedded SQL run faster than my stored procedures? A: Re-compilation may be the reason why the stored procedure runs slowly. To confirm this, you need to perform some performance tests, such as checking the "showplan" situation of each type of queries and calling stored procedures, compare the high-speed cache hit rate and high-speed cache miss rate of the query plan. You can also write the object owner for the referenced tables, views,
