1. Memory Protection Unit MPU Similar to Cortex-M3, MPU is an optional component used for memory protection in Cortex-M4. The processor supports the standard ARMv7 memory protection system structure model. You can run privileged/access rules or independent processes on the MPU. This MPU provides comprehensive support: · Protected Area · Overlapping protection areas to improve the priority of the Region (7 = highest priority, 0 = lowest priority) · Acc

CORTEX-M3 has universal register R0-R15 and some special function registers. R0-r12 is the most "common purpose", the vast majority of 16-bit instructions can only use R0-R7, while the 32-bit Thumb-2 instruction has access to all the universal registers. Special function registers must be accessed through a dedicated instruction.Universal Purpose Register R0-R7R0-R7 is called a low group register. All instructions are accessible, R8-r12 called High gr

Translated from FreeRTOS official website document, original website: http://www.freertos.org/RTOS-Cortex-M3-M4.htmlReprint: Original source: Http://bbs.ednchina.com/BLOG_ARTICLE_3009240.HTMThousands of FreeRTOS applications run on the arm cortex-m core. Surprisingly, the RTOs is used in combination with the Cortex-m kernel, making the request for technical support so much less. Most of the problem points are caused by incorrect priority settings.

At present, the most common embedded operating system on the CORTEX-M3 platform is ucosii, in addition to support the mainstream embedded operating system is difficult to see, this is because CORTEX-M3 frequency is low (common 72M), does not support MMU, In-chip flash and in-chip ram are relatively small and so on, these limitations, such as wince system, embedded Linux, such as the need for MMU support sys

Windows 7 M3 Build 6801.0.080913-2030 (hereinafter referred to as: Win7 M3) The test results in the virtual machine satisfied me, the system stability is quite high, which gives me enough information to Win7 M3 directly run on my notebook. In the morning, the direct redo of my notebook system, because X60 does not have the optical drive, I use before on the mobil

Typically exceptions include some system exceptions, as well as interrupts.Exception TypeThe CORTEX-M3 processor supports multiple types of exceptions: RESET, NMI, HardWare Fault; Psv,svc and other programmable interrupts; Other programmable interrupts, such as Timer,gpio. The priority of the 1th class of exceptions is fixed and immutable. Everything else can be modified.The CORTEX-M3

As one of the most beloved third Fangan of the brush player, CyanogenMod has always been known for its fast upgrade and wide support equipment. CM11 nightly test version just released, more stable M3 snapshot again. According to CM's published practice, nightly is completely new to the nature of the code, but there will be a lot of bugs, stability is not guaranteed. Snapshot m is updated about once a month, with less nigtly bugs and fewer problems, a

First, background:Recently, a project has been taken over, the core chip is both the LPC17XX series MCU, core arm of the COTEX-M3 core.If you want to play with an MCU, you have to take care of its clock!The clock is to the MCU, like the human heart. It gives the AHB, APB Bus The blood (clock frequency), and the devices that hang on the AHB (Advance High bus) bus are like our various organs, the peripherals that hang on the APB (Adance peripheral bus)

Comparison of CORTEX-M3 and ARM7In March 2005, ARM announced the latest ARMV7 architecture and defined three major series:the "A" series is designed for cutting-edge virtual memory-based operating systems and user applications. Mainly for the growing running of consumer electronics and wireless products including Linux, Windows CE and Symbian;The "R" series is for real-time systems. Mainly for systems that need to run real-time operating systems for c

Today the company's IBM x3650 M3 to strike, fortunately, the data in the basic is not needed, you can kill the reload. It used to be a lot of servers to contact Dell, so the IBM server was really smattering, and now it's just a chance to know I'm not going to let go, so I started starting with the initial reconfiguration of the disk array raid.First, RAID configurationon this part, I think a lot of people have written such articles, so I do not write

When the CentOS IBM system X3650 M3 server is installed on the IBM X3650 M3 and CentOS 5.5 is directly installed on the CD, the disk cannot be found at the partitioning step, you must manage the hard disk and set it to raid0 before installing the linux system. If the server displays "+" during self-check, you must set the disk to install the operating system. If "+" appears, you can directly install the ope

In the next line of the first function systeminit (), there will be another common function.Nvic_prioritygroupconfig (nvic_prioritygroup_x)(X indicates numbers 1, 2, 3 ...). This function is related to the interrupt configuration. It configures the interrupt priority, including the preemption priority and subpriority.

the following figure. The CPU is in thread state, working with the PSP stack, and the PSP points to the TASK1 stack. Each register in the CPU is the register value of the Task1 current task. The TASK2 is in a suspended state, and the TASK2 stack pointer is saved by the TCB2 SP variable. At the bottom of the Task2 stack, two pieces of data are saved, part of the register variable (including XPSR,PC,LR,R12,R0~R3) that is automatically saved to the stack when the CPU breaks, and the other is Ucos
