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

Python2.6 is just released in 10.1. I can't wait to write this introduction before reading it carefully. There are too many exciting new improvements. 2.6 is directedPython3.0 (python3000) is a new step and is not compatible with the python2.x sequence. I carefully read the newly addedProcessing of multi-process packet group multiprocessing (PEP 371), which is a weapon developed by python to take advantage of services gradually b
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
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

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:

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 called the "Soc" (on-chip system), and the m
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

Most of the "mediocre" students, who have excellent intelligence since childhood, get high scores each time without spending too much time doing their homework, because, those students
The detail parameters of the processor, features supported features summed up very complex, want to say it may take a long time, but for ordinary consumers do not need to know so many irrelevant technical indicators, for the mass consumer groups as long as you know which performance is good to help the decision to buy this is enough, So today we say that the mobile version of the processor in the notebook,

1. Introduction to ARM programming
• In the development of embedded systems, the main programming languages currently used are C and assembler. In many places, such as the initialization of hardware system at boot time, including the setting of CPU state, interrupt enable, the setting of the main frequency, as well as the control parameters and initialization of RAM are used in assembly language. Assembly la
