Automated Testing reads and writes the 64-bit operating system registry, read and write 64-bit Non-Web programs (desktop programs) are usually set in the registry. When performing automated tests on these programs, you need to deal with the Registry frequently. Modify the settings of a program by modifying the registry. This chapter describes how to use the C # p

System ResourcesThe RTX kernel identifies a task process through the task Process Control module. This module is a dynamically allocated memory unit that stores all the control and state variables of the task process. When a task process is created by calling the os_tsk_create or os_tsk_create_user function, the corresponding TCB is created.The amount of memory that the TCB occupies, as defined in rtx_config.c .The RTX kernel assigns its own stack to

As we all know, CPU is the fastest part of the computer system, while external devices are the slowest part. There is a big difference between them. However, the CPU may always require access to peripherals. If each CPU operation has to wait for the completion of the peripherals, the valuable running time of the CPU will be greatly wasted. With the development of modern computer technology, most modern operating
