ARM processor status
The ARM microprocessor generally has two working states and can be switched between them:
The first type is the arm State. At this time, the processor executes the 32-bit arm command;
The second is the thumb State. At this time, the processor executes the 16-bit half-aligned thumb command.
During the execution of a program, the microprocessor
ARM Processor ModeThere are 7 modes of operation for ARM processors:
L user mode (USER,USR): Normal program execution mode
L Fast Interrupt Mode (FIQ,FIQ): For high-speed data transfer and channel processing
L external Interrupt mode (IRQ,IRQ): for normal interrupt handling
L Privileged Mode (SUPERVISOR,SVE): A protected mode for use by the operating system
L Data Access Abort mode (ABORT,ABT): for virtual storage and storage
Q: Often in newspapers and magazines to see the word dual core processor, what is the dual core meaning? What's the benefit?
A: In simple terms, a dual-core processor is the integration of two CPUs on a single wafer. So what is a dual-core processor? What does the concept behind a dual-core processor mean, in short, a

Unfortunately in the first few days "Oracle operation and maintenance of the high-level team" on. BBQ God says a lot of rhel bugs. This bug in this example, the following URL:https://access.redhat.com/solutions/433883There is no problem with Red Hat Enterprise Linux 5 kernels.It is also recommended that you install the rhel6.5 version number in a production environment.The detailed description is described in the following posts:https://access.redhat.com/solutions/433883The following full text r
I will upload my new book "self-writing processor" (not published yet). Today is the eighth article. I try to write this article every Thursday.
2.7 Circuit Design Example
In this section, we will design a simplified processor command acquisition circuit, through which we can use the example to understand the use of Tilde.
There is usually a PC register inside the proc
I will upload my new book "self-writing processor" (not published yet). Today is the fifth article. I try to write this article every Thursday.
Based on the introduction in the previous chapter, you should know that the CPU has some basic circuits, such as decoding circuit, calculation circuit, control circuit, and some registers. How can these circuits be implemented? Of course, it can be achieved through a lot of discrete components. In fact, in 20
In addition to the bean post-processor discussed in the previous article, spring also provides a container post-processor.Bean post-ProcessorProcesses All bean instances in the container, whileContainer ProcessorIt is responsible for processing the container itself.
The post-container processor must implementBeanfactorypostprocessorInterface, which has a method:

The 64-bit processor must have the following points:
1. Complete 64-bit registers
2. Complete 64-bit commands
3. In terms of memory addressing, in theory, a 64-bit processor should have a 64-bit addressing capability, that is, it can address such a large space as the 64-power of 2, however, in actual hardware implementation, this is not exactly the case. For example, AMD's athlon
There is a huge opportunity to migrate games and other applications that use a large number of 3D graphics from OpenGL to Google Android devices, including devices built on Intel's atom micro-architecture, because OpenGL-based games, game engines, and other traditional software are easy to obtain, OpenGL is easy to transplant, and Android can provide OpenGL ES and C/C ++ support. Even, the availability of many OpenGL-based games and engines is the same as that of open-source Software, such as th

Intel Core i5 and i7 can be said to be the most mainstream desktop processor in the market, with a large number of laptops and desktops using these two processors. So, if you want to buy a computer, should consider i5 or i7? Look at the major differences between them.
Hyper-Threading
Hyper-threading means that each processor core can handle two threads rather than one, with better performance
A few days ago, ARM launched a low-power 64-bit server processor, coupled with Intel's Atom processor, to repeat the low-power server market. Although few users are preparing to purchase such servers, suppliers such as Dell and HP have joined the ranks of low-power servers. Among them, HP said it included the development of low-power servers in the latest product released by Project Moonshot, and will use I
