can only be performed when the task is returned from the soft interrupt context, in fact CORTEX-M3 supports this stack model, the CPU provides MSP and PSP two stack pointers, when interrupts automatically switch from the user-state PSP to the MSP, the benefit of the global kernel stack is that all tasks share a kernel stack, The maximum stack depth of the kernel is predictable, and different tasks executing at the non-privileged level require differe

As X86 servers become homogeneous, can we make any decision on server selection? The answer is, of course, whether the rapid development of business needs of today's enterprises puts forward higher requirements on server scalability, performance, reliability and management, servers not only require excellent computing performance and architecture, but also excellent management functions, which can help users simplify server management and improve the efficiency of enterprise IT architecture mana

How to recommend. One solution is to predict the possible scores of A's ungraded songs based on the data. Then a ranking is made based on the prediction. Recommend the music of topn to. Then, the question we need to solve next is how to predict. User-based collaborative filtering is performed by users like afor p
