This blog post focuses on the features and functions of the CPU registers around the base part of the registers in the 80x86 CPU.ObjectiveFirst, let's introduce the history of Intel CPUs.Intel CPU Series, initially 4-bit microprocessor 4004, then to 8-bit microprocessor 8008, then 8-bit microprocessor 8080, and later 16-bit microprocessor 8086.Starting from 8086, Intel entered the so-called x86 era.Intel 80
CPU usage depends primarily on what kind of resources are running on the CPU, such as copying a file that typically consumes less CPU, because most of the work is done by DMA (Direct Memory Access), but after the copy is complete, the CPU knows that the copy has been completed. Scientific computing usually takes up mor

Indicator Range 1.1 User mode CPU utilization+ System Mode CPU UtilizationReasonable value: 60-85%, if the us+sy time in a multiuser system exceeds 85%, the process may take time to wait in the running queue, the response time and business throughput will be compromised; the US is too large to indicate that there is a user process that consumes a lot of CPU ti

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names:
1. CPU external frequency = External frequency
2. CPU frequency = clock speed
3. Frontend bus frequency
4. System bus frequency
5. MultiplierRelationships:

In fact, the people who write Java seems to have nothing to do with the CPU, at most and we mentioned in the previous how to run the CPU full, how to set the number of threads is a bit of a relationship, but the algorithm is only a reference, many scenarios need to take practical means to solve can And we'll consider how to make the CPU not so full after the

FOTA-Air firmware upgrades guide
Sudden 1. Overview and requirements.
Overview:
1. FOTA represents an aerial firmware upgrade.
2. This is a program where end users can upgrade their mobile software "in the Air".
3. The connection to the PC system is not required.
4. This procedure is provided through 3G and Wi-Fi networks. However, if you upgrade over a 3G network, the download will generate additional costs.
Requirements:
1. Stable network status (3G or Wi-Fi).
2. Adequate battery ca
Because of the management problems in our alization are caused by the annoyingly popular desirable host Migration Feature! I previusly talked about PCI device addressing problems, but this time the topic to consider is that of CPU models. every hypervisor has its own policies for what a guest will see for its CPUs by default, xen just passes through the host CPU, with qemu/KVM the guest sees a generic mode
Without nagios monitoring software, as long as the server can access the Internet, you can send an email to remind the administrator of the system load and CPU usage.

The best synchronization technology is to put the design of critical resources that do not need to be synchronized first. This is a way of thinking, because each explicit synchronization primitive has a performance overhead that cannot be ignored.
The simplest and most important synchronization technology includes declaring kernel variables or data structures as per-CPU variables ). Each CPU variable is mai

After introducing the origins of parallel imports of boxed processors, we will briefly introduce some of the other informal processors in the market in order to improve consumers ' purchasing awareness.
Introduction to parallel imports of bulk processors:
In the bulk processor market, parallel imports are not

Most of the ROM is currently customized using cm, and part of the official original ROM is modified, only a small part of the ROM is modified AOSP source code, these ROM points are the Google Nexus series of models, such as Galaxy Nexus and Nexus S on the codename and AOKP, on the source to do a lot of changes, so that the m
Let the multi-core CPU usage curve listen to your command-the beauty of programming 1.1 Study Notes Problem:

2. the CPU usage is a straight line. The specific
With the increasing popularity of Linux applications, a large number of network servers use the Linux operating system. To fully measure the network running status, you need to make more detailed and accurate measurements on the network status. The establishment of the SNMP protocol provides powerful support for Internet measurement. Multirouter Traffic Grapher (MRTG) is a typical network traffic statistical analysis tool based on SNMP. It consumes a small amount of system resources, so many plu
CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. Higher usage means that your machine runs a lot of programs at this time, whereas lessThe top command is a common system performance analysis tool under Linux that allows you to view the resource usage of each process in real time.Top-10:02:17 up (19:18), 4 users, load a
