1, Overview 1. Process: The running program is an independent unit for the system to allocate and call resources. Each process has its own memory space and resources. 2. Thread: It is a single sequential control flow of a process, or a separate execution path If a process has only one execution path, it is called single thread If a process ...

The previous analysis shows how the android HAL layer searches for the dynamic shared library of hardware modules. In fact, it is to find the shared library modueid under the two paths of "system/lib/hw /" or "/ vendor/lib/hw /" variant. After so, load the library by calling the load function. Now let's enter the load funct ...

After going through many difficulties and obstacles, it reaches the network card of this computer. This process can be read If you design the network Anyway, now ...

Backtracking algorithm is actually a similar exhaustive search attempt process, which is mainly to find the order of the problem in the search attempt process. When it is found that the solution conditions are not met, it will "backtrack" (i.e. backtrack) and try other paths. Therefore, backtracking method is known as "common pro ...

Introduction: This paper introduces how to test the memory access delay of multi-level cache and the computer principle behind it.The CPU cache is often a multi-level pyramid model. L1 is closest to the CPU and has the smallest access delay, but the cache capacity is also the smallest. This paper introduces how to test the memory access delay o ...
