Interrupt handling of ARM processors1) There are 8 operating modes in the arm processor (and the CPU handles different task modes), typically 5 Abnormal mode, In these 5 Modes There are three interrupt mechanisms, namely the FIQ mode (High priority interrupt mode);IRQ Mode (Low-priority interrupt mode), and one that is the SVC mode (the mode generated when the reset or soft interrupt (SWI) instruction executes)2) First understand what the interrupt m
The history of 64-bit computing is quite rich and interesting. Companies such as Cray have started using 64-bit registers in their systems in the 70 's, but the truly pure 64-bit computations didn't really come until the 90 's. The first is the R4000 of MIPS, then the DEC Alpha processor. By the middle of the 90, both Intel and Sun had 64-bit designs. The real turning point for consumers is that AMD released a 64-bit PC
Linux supports a single system with multiple processors. Except for the boot process, the process scheduling program is responsible for a large amount of work that supports multiple processors. In Symmetric Multi-processing (SMP) and above, the process scheduler must determine which processes are running on each CPU. Two challenges arise from this responsibility: the scheduler must make full use of all the processors in the system, because when one process is ready to run, one CPU is idle, this
I will upload my new book "Write a processor by myself" (not published yet). Today is the beginning. I try to write an article every Thursday. Introduction In this book, we designed and implemented openmips, a processor compatible with the mips32 instruction set architecture. The openmips processor has two versions: Teaching edition and practical edition. The m
Recently, the hype over dual-core processors has been so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel are praising the merits of their dual-core processors through their websites. Such campaigns are timely, as most industry watchers believe the dual-core processors will be in the pipeline in 2006. But behind these phenomena, and in the many related media reports, there are hidden truths that are not known and unusual. Below, we'll tell you
Multi-tasking operating systemThe operating system provides a mechanism for the virtual processor, which gives the process an illusion that the process feels like it is monopolizing the CPU. The operating system kernel must pass reasonable process scheduling to ensure this illusion, so that the operating system resources to get the maximum utilization.It is this virtual processor mechanism that allows the o
Article Title: Understand the average processor load of Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. You may have a good understanding of the load averages in Linux. The average load value can be seen in the uptime or top command. They may look like this: Load average: 0.09, 0.05, 0.01 Many people will un
Why is the actual frequency of only 2500g amd + processor running faster than the actual frequency of 2G P4-2.4B is faster? Why is the tulatin core processor with a 0.13 micron process capable of achieving a maximum of 1.4 GB? Instead, the Willamette core processor with a 0.18 micron process can easily achieve 2 GB? Next, let's analyze why the above two "strange
Assembled computer friends generally must have a certain understanding of computer hardware, must understand its balance, the balance between components and hardware performance, processor is computer enthusiasts are very concerned about, so what kind of processor is a good processor (CPU)? Generally we look at the main proce
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

This chapter is selected from the Intel official documentation and translated by myself. Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage. Intel 64 and the IA-32 architecture provide the ability to manage and enhance the execution of multiple processors connected to the same system bus. These include:
period.APTAnnotation Processing Tool is a built-in Tool for javac to scan and process Annotation information during compilation. From JDK 6, apt exposes available APIs. A specific processor receives a Java source code or compiled bytecode as the input, and then outputs some files (usually. java files ). This means that you can use apt to dynamically generate code logic. Note that apt can only generate new Java classes and cannot modify existing Java

Processor Scheduling Model and Scheduling Algorithm in OSProcessor Scheduling Model and Scheduling Algorithm in OS Scheduling level 1.1. Advanced scheduling (long-range scheduling and Job Scheduling) Function: According to an algorithm, the jobs in the backup queue in the external storage queue are transferred to the memory, and the job is the operation object. Job: A more extensive concept than a program. It not only contains common programs and data
the Hardware Management Console (hardwareManagement Console. 2. Problem Solving: After introducing the concepts of "slot" and "lpar", how can we check the number of slots or lpar of the current machine? First of all, we need to know that lpar has many applications on Minicomputers, and is rarely used on x86 servers. To view the number of slots, run the following command: [Root @ compute-30-02 ~] # Lscpu | grep "CPU socket" CPU socket (s): 2 Command to return the result. The number of slots on t
