Embedded systems (Embedded system), generally refers to non-desktop computer systems (that is, non-PC, server, small and medium-sized machines, etc.), computer functions and can be "embedded" to special equipment and play a special function of computer equipment or equipment. It is the application-centric, hardware and software can be cut, to adapt to the application system to function, reliability, cost, v
illustrate this problem more vividly, we can give some examples. such as personal computers, the reason for the rapid development in decades, the final brewing of the information technology revolution, the most fundamental factor is that it has a standard architecture, that is, IBM compatible machine architecture. Since the architecture is standard, it means that mass production can be produced, and many PC manufacturers emerge, providing the material foundation for the information revolution.
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
