When flash is connected to the CPU, according to different data width, such as 16-bit nor flash (A0-A19), the processor address line to (A1-A20) shift left to 1. Why is it one-digit?
From the perspective of software and CPU, an address corresponds to one byte, which is 8-bit data. This is for sure. Do not doubt this.
For a specific device, its bit width is certai
Every version of Microsoft Internet Information Service (IIS) is like a part of the novel series. This novel is published several years ago, but it proves to be worth waiting.
IIS8 will be released with the beta version of Windows Server 8. IIS8's new feature aims to bring together large-scale Web servers. However, a good result of all functions is how to allocate smaller servers or even separate servers.

On July 6, July 24, Windows 8 Server version Hyper-V no longer has CPU kernel restrictions. It was previously reported that Windows 8 will directly have built-in Hyper-V 3.0 components, but it was mentioned that there may be restrictions on multi-core CPU. Recently, microsoft's Grant holistically releases the message t
When Windows 8 uses Windows Media player to play music. In fact there is one such situation, WMP and some what name looks very big cock process run CPU very high, this run very high depending on the number of files that you inserted in the SD card or the number of files on the removable hard disk. Assuming there are so many files, this will run to get the system up and running.Just like this:Reason:WMP comm

When Windows 8 uses Windows Media Player to play music, there is actually a situation in which WMP and what the name looks like are very high on the CPU, this run is high depending on the number of files in the SD card you insert or the number of files that are moving the hard disk, if there are many files, This runs to get the system to die quickly.Just like this:Reason:WMP commands the WPD system service
Solution:1. The driver has not been certified, resulting in 100% of CPU resources. A large number of beta drivers are flooding the Internet, leading to hard-to-find fault causes.2. Faults caused by anti-DDoS and anti-virus software. Some anti-virus software has added random monitoring of web pages, plug-ins, and emails, which undoubtedly increases the burden on the system. You can choose to enable the service as needed.3. Viruses and Trojans. A large

. Therefore, we need to adjust the registers according to the order of instructions, how to arrange appropriate registers to avoid the transfer operation of too many operands is a very meticulous task, there are some specialized register allocation policiesArticleIn the Book Compilation principles.
16/32-bit CPU is often used in PC, so the names and specific functions of the internal registers of these two CPUs are introduced.
1. 16-bit
I will upload my new book 《Write CPU by yourselfToday is 35th articles. I try to write articles every Thursday.
8.3 Transfer Instruction Implementation ideas 8.3.1 Implementation ideas
According to the discussion in section 8.1, in order to minimize the loss caused by the transfer instruction, openmips judges the transfer condition in the decoding phase. If the transfer condition is met, modify the PC as the transfer target address.8.3.2 modify a data
simulation 7-14 is shown. We can see that the multiplication, accumulation, and multiplication, and subtraction commands are correctly implemented. At the same time, we can see that the multiplication, accumulation, and multiplication, and subtraction commands require two clock cycles to be completed.
