Composition Of Embedded System | |
An embedded system is used in the above-mentioned industries. An embedded system is composed of hardware and software and is a device that can operate independently. According to the architecture, the embedded system is divided into the hardware layer, middle layer, system software layer, and application software layer. The hardware layer includes an embedded microprocessor, memory, common device interface, and I/O interface, which is the core of the embedded design system. In addition, the memory is located between the main memory and the embedded microprocessor core, which stores the most used program code and data of the microprocessor in recent times. Its main goal is to reduce the memory access bottleneck caused by the memory to the microprocessor core and make the processing speed faster. The middle layer, also known as Hardware Abstraction Layer HAL or Board Support Package BSP, separates the upper system software from the underlying hardware so that the upper system software developer does not need to relate to the specifics of the underlying hardware and can develop according to the interface provided by the BSP layer. Designing a complete BSP requires embedded system hardware initialization and BSP functions, as well as designing hardware-related device drivers. The system software layer consists of RTOS, file system, GUI, network system, and common component modules, where RTOS is the foundation and development platform for embedded application software. touch screen module https://www.stoneitech.com/ | |
