After the acquisition of the Msnlite team, the millet company launched a rice chat earlier this month in the PC version of the beta. Today, the meter chat PC version of the public test (version number is 1.0.0.5009), all users can download experience meter Chat PC client. M-Chat PC version has three main features: bri

system's tasks require access to all system resources, while the task still uses the user-mode register group instead of using the appropriate register group in the exception mode, which guarantees that the task State will not be destroyed when an abnormal interrupt occurs. ARM processors are available in 7 different processor modes, with a set of corresponding register groups in each of the processor mo

that the operating system is very eager to hit the level 2 cache each time, because this will save a lot of time to reload the data from memory into the slice cache. Most operating systems do not have a lot of computational data to deal with, so these tasks do not require much concern about the caching of the slice. At the same time, most low-end servers do not have very large cache, so they are less concerned about the problem. But for SQL Server running on a server with a larger cache, the p

Multi-processing, Similar to SMP, is also an OS Management of all cores, but the difference is that, in BMP, Developers can specify that a task be executed on only one of the specified cores. 4.terminology related to multicore processorsAp-application Processor, application processorBp-baseband Processor, baseband processorThe above appears in the mobile phone more, some will integrate the two into a sili

Before IBM launched the world's first personal computer in 1981, computers were used in commercial or industrial use. With the birth of IBM 5150, personal computers have truly entered people's work and life, but also marks the beginning of a new era-the personal computer era. In the next thirty years, with the development of computer and network technologies, personal computers have developed towards a more intelligent, portable, and easy-to-use trend. The advent of the portable laptops, PDAs

Nowadays, the input method, as a necessary tool for inputting text into computers and smartphones, has been paid more and more attention by many internet companies. In addition to the integration of the Microsoft Pinyin Input method, Windows7 also provides Tablet PC Input Panel tools, can be handwritten, but also the phrase association, the function is very practical. Let's take a look at the Tablet PC Inpu

implementation of Xxx_contextswitch is generally as follows {Move the current task's stack pointer to make a memory save the current task's context find the next stack pointer to run the task to restore the context of the next task, The last step is to assign the saved PC value to the CPU register} There is a need to introduce two "original concepts": full context and partial context. The full context is the variable register content that is used in

The previous chapter describes how C is translated into assembler and how the assembler is used. But how is the assembler implemented? For example (add%eax%edx) This instruction, we know its function, how does the processor execute the instruction to get the desired result? -This is the subject of this chapter.(i) Y86 instruction set architectureTo simplify the problem, we do not use the instruction set architecture of Intel and ATT to abstract simpli

Fourth Chapter processor Architecture 4.1 Y86 instruction set architectureDefines an instruction set architecture, such as Y86, that includes defining various state elements, instruction sets, and their encodings, a set of specifications, and exception event handling.4.1.1 Programmer-Visible State① programmer Visible State: Each instruction in Y86 reads or modifies portions of the processor state.

In the previous part1, I explained the various stages that the 3D rendering command had taken before being actually processed by the GPU on the PC, and then dug a hole here with the instruction processor. OK. In this part, we will indeed encounter the instruction processor first, but you need to know that everything in the instruction buffer goes through the memo

Many Netizens hope to connect to the PC network using the Bluetooth of a smart phone so as to achieve the Internet access through the mobile phone (note that the difference is different from the GPRS of the mobile phone used by the PC). The benefits of doing so are: high speed (much faster than GPRS), no money (using a PC Network ).. there are few introductions o

Do you think it's just a CPU when you lift a phone processor? What, you always think so? Well, boy, it's naïve. Have you heard of the "core M" processor in the PC field? The processor, which can be plugged into a tablet, laptop or computer, is not a single processor, but is

For wireless system design engineers, it is critical to have a clear understanding of the differences between multithreading (MT) on a single processor and using multi-processor (MP) processing. Cellular phones are the first large-scale application to implement dual-core design. However, dual-core implementation is also applicable to many wireless applications that require high performance and low power con
