Understanding the system structure from the Java perspective serial, follow my Weibo (link) Learn about the latest developments it is well known that the CPU is the brain of the computer, which is responsible for executing the instructions of the program; Memory is responsible for saving data, including the program's own data. As we all know, memory is much slower than CPU. In fact, 30 years ago, the
In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a pulse signal) per unit time. The standard unit of measurement for a frequency is Hz ). The system clock i
How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the computer Pepsi network finally brought the CPU ladder Figure 2016 the latest version, through the latest CPU ladder diagram, can fully understand the computer processor performance. This provides 2016 of the latest

Knowledge about Linux CPU and Linux CPU
What is the difference between hyper-threading and multithreading?
Hyper-threading is understood from the hardware layer, that is, a CPU component (which can be understood as a core) executes multiple commands at the same time, which means that multiple threads are executed at the same time.Multithreading is a concept at th

Enter the command: cat/proc/cpuinfo
Check the number of physical IDs in the output result. If 0 is displayed, there is only one physical cpu;
Check the number of processor output results. If there are 0 and 1, there are two logical CPUs.

Intel Atom processor-oriented netbook needs to solve the problem is the price and power, to arm or even MIPS-oriented domestic netbooks need to upgrade the performance, both of the target is supplemented by video, GPS, television features of the netbook products, but Intel and via from the laptop to the low-end penetration , domestic processor manufacturers from MP4 to high-end, X86 and arm real confrontation should be in 2010 years.

Article, where the information may have evolved or changed.
First, the conclusion is listed in the front:
Golang performance can be very good, but some native package performance is likely to be retarded, such as RegExp and Encoding/json. If used in high performance requirements, we should optimize according to the actual situation.
The use of ON-CPU/OFF-CPU flame dia
the difference between CPU bulk and boxed
From the technical point of view, the bulk and boxed CPU is not the essence of the difference, at least in terms of quality and performance does not exist problems, more impossible to have a fake CPU (no manufacturers can counterfeit such high-tech products), of course, do not rule out profiteers after grinding to low fr
Possible factors:1. Ambient temperatureThe cpu temperature has a lot to do with the ambient temperature. It will be a little higher in summer. Generally, the temperature is less than 50 ° when the CPU is idle, less than 65 ° when the CPU is busy, and less than 75 ° when the CPU is working at full speed. In
Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs.
For details, FSB is P
Ways to handle excessive CPU temperature
One, clean CPU cooling fan
1 The easiest and most cost-effective way to do this is to use the brush and the fur tiger to clean the fan of the CPU heatsink and to improve the processor's thermal performance after the cleanup.
2 cleaning the fan is a need for patience, and the fan's dead end is not
Bit and word length of 1.CPU
Bit: in digital circuits and computer technology using binary, code only "0" and "1", which either "0" or "1" in the CPU is a "bit."
Word Length: The number of digits in the computer technology that the CPU can process at one time (at the same time) is called word length. So the CPU tha
1 socket, core, thread(1) Socket is the number of slots on the motherboard to plug the CPU, that is, the administrator said "road"The chip manufacturer encapsulates one or more cores on a chip, called a socket. Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on. Single-core (Single-core) and multicore (multi-core) are also k
First, the concept① Physical CPUThe number of CPUs in the actual server slot on the physical CPU, the number of physical IDs that can be repeated is several② Logical CPU③CPU Number of coresThe number of chipsets that can process data on a CPU, such as the current i5 760, is a dual-core four-thread
CPU instruction design, in addition to naming, it is more important to analyze how the instructions can be achieved. For the CPU structure of Figure 3 1, if the instruction is pre-placed in the Irom, then the instruction is executed with one piece of irom removed from the IR instruction register and provided to the control for analysis execution. How each instruction is transformed into a machine action, th
CPU is the core of the computer hardware, but also the computer hardware in the heat, so the CPU cooling fan speed, the fundamental computer cooling. What about the CPU fan speed? Generally you will choose to see the BIOS settings, but the BIOS needs to restart the computer, and the operation is relatively complex. Today, the WiFi sharing master teaches you a ver

Within a period of time, adjust the CPU usage display by controlling the CPU busy time.

CPU fan speed too slow on the CPU is very large, light will cause frequent computer crashes, heavy will cause the CPU burned, and even burned the motherboard and other electronic components, resulting in a great loss, but the CPU speed too fast on the computer and what effect? is the
CPU utilization good understanding, that is, CPU utilization, more than 75% is higher (also has the argument is 80% or higher). In addition to this indicator, but also in combination with the load average and context Switch rate, it is possible that the high CPU is due to the latter two high indicators.
Load Average, this is hard to measure. Online Search a la
