Linux supports a single system with multiple processors. Except for the boot process, the process scheduling program is responsible for a large amount of work that supports multiple processors. In Symmetric Multi-processing (SMP) and above, the process scheduler must determine which processes are running on each CPU. Two challenges arise from this responsibility: the scheduler must make full use of all the processors in the system, because when one process is ready to run, one CPU is idle, this

Contact Email: feixiaoxing @ 163.com] Before I started working in a chip company, I knew very little about the chip design. I knew a lot about the chip company datasheet. There is no such resource, and there is no such requirement. However, when I came to a new company, especially after I realized the open-source CPU, everything had changed. Open-source CPU-based code, open-source code compil

A foreign hacker named Dmitry grberger tried to create an eight-bit simple computer micro-control device and run Linux on it. He wrote an ARM Simulator: Two hours after the startup, he saw the command line prompt (init =/bin/bash). Four hours later, he saw the Ubuntu logon page. After logging on, the system is still available to some extent. after entering a command, you can see the response within one minute. Generally, Linux does not run on systems with less than 32 bits. Therefore, grbe

The NAND boot steps:The Sector Media boot steps:(Sector Media devices include SD, SDHC, MMC and Movinand)1.A2S/A2M 硬件启动程序boot-strap在片上ROM。2.boot-strapper初始化sector media devices(上电启动配置选中的设备)3.boot-strapper从sector media中读取DRAM配置，初始化DDR2控制器及DRAM设备。4.boot-strapper从sector media 的 sector1读取配置，并加载boot-loader到DRAM，最后将PC置到boot-loader。5.boot-loader初始化MMU及分页表。6.boot-loader从sector media主分区中读取 RTOS/APP raw image至DRAM，并解压的最终地址（DRAM）。7.boot-loader从sector media的DSP分区

Multi-tasking operating systemThe operating system provides a mechanism for the virtual processor, which gives the process an illusion that the process feels like it is monopolizing the CPU. The operating system kernel must pass reasonable process scheduling to ensure this illusion, so that the operating system resources to get the maximum utilization.It is this virtual processor mechanism that allows the o

, but it is sufficient for emergency use. The mini computer reminded us of a Guleek i8 computer released last year, which has a lot in common, the only difference being that the Cloudsto X86 Nano PC can also act as a mobile power for smartphones. In terms of internal specifications, the Cloudsto X86 Nano PC uses the Intel Atom z3735f processor, which may be some

Article Title: Understand the average processor load of Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. You may have a good understanding of the load averages in Linux. The average load value can be seen in the uptime or top command. They may look like this: Load average: 0.09, 0.05, 0.01 Many people will un

Why is the actual frequency of only 2500g amd + processor running faster than the actual frequency of 2G P4-2.4B is faster? Why is the tulatin core processor with a 0.13 micron process capable of achieving a maximum of 1.4 GB? Instead, the Willamette core processor with a 0.18 micron process can easily achieve 2 GB? Next, let's analyze why the above two "strange

Assembled computer friends generally must have a certain understanding of computer hardware, must understand its balance, the balance between components and hardware performance, processor is computer enthusiasts are very concerned about, so what kind of processor is a good processor (CPU)? Generally we look at the main proce
