Porting and testing of embedded real-time operating system Μc/os-ⅱ on DSP chip

Board. The test proves that the operation of the operating system in DSP chip can be tms320c6713, the reliability is guaranteed, and the real-time performance is greatly improved. At the same time, the porting method introduced in this paper has a strong universality in the same kind of DSP architecture processor, and it also has some instructive meanings to the porting of Μc/os-ⅱ

Acer's installation of the Linux system could not find a workaround for the operating system.

Recently installed the linux,ubuntu15.04 system on a notebook. I did a U disk Boot disk installation, installed after entering Blos set Ubuntu as the first startup item.After that, restarting the computer shows "unable to find the operating system" and is finished. No way, it is estimated that the issue of the start item, search on the internet, found a super pow

Feasibility analysis of domestic operating system

friendly user interface is valuable, but there are a few ways we can get to the OS's technical sources. One is like Bill Gates of the year, starting from the bottom of the programming, to make a "fully domestic" operating system. Needless to say, everyone knows it's almost impossible. The other is like Linus, rewriting the source code of Minix, this is a relatively good way to go, but to make minix for com

functions, for example, some methods only have a higher version of the API, the use of the lower version will cause the program to crash. But there is another scenario that leads to a third way to fix the usage scenario: most of the operating systems are open-source, and Google's Android is the default, but don't forget the Meizu flyme OS and Xiaomi Miui, which are variants of Android. If using non-Xiaomi mobile phone also installed MIUI, the latter

Analyze the real-time operating system from the task scheduling mechanism

method that runs multiple operating systems. When this method is used, the ultra-micro kernel abstracts hardware in real-time and non-real-time kernels. This is similar to how hypervisor abstracts bare metal machines from the customer's (guest) operating system. An example of an ultra-micro kernel is the adaptive domain environment for

China Mobile's scale-up strategy: self-developed BC-Linux operating system, with over deployments!
