In the fierce competition of the global chip market, X86 and ARM architectures have always dominated. However, in recent years, a Chinese independent CPU manufacturer, Loongson, has been challenging these two traditional giants with its unique strategy and firm determination. Loongson’s goal is not only to occupy a place in the domestic market but also … Read more
How to keep your app running continuously? By default, if no cross-process deployment configuration is made, each Android app runs in a separate virtual machine, with each virtual machine corresponding to a process. When the app is reclaimed by the system or actively killed by the user (through app management software), the process exits completely. … Read more
In most cases, application code can be written in C or other high-level languages. However, having a basic understanding of the instruction set supported by Cortex-M processors helps developers choose the right Cortex-M processor for specific applications. The instruction set (ISA) is part of the processor architecture, and Cortex-M processors can be divided into several … Read more
Sitting on the high-speed train from Shanghai to Beijing, the long journey really makes one feel bored (I couldn’t get a direct train, so I can only go slowly, stopping at every station. It’s ridiculous that in the high-speed train era, it still is like this. It reminds me of the time in college when … Read more
To not miss my updates, remember to check the public account in the upper right corner and set it as a star, take down the stars and give them to me. Last month, we shared our treasured boards for everyone to learn and use. The first batch of users who received the boards shared their … Read more
1. Concept SMARC (Smart Mobility ARChitecture) is a generic definition for small computer modules based on ARM and X86 technology, designed for low-power embedded architecture platforms aimed at meeting the needs of low power, low cost, and high performance applications. These modules typically use ARM SOCs similar to those found in tablets and smartphones, or … Read more
