Computer memory, is the temporary storage area of a computer, which holds the data and instructions needed by the Central Processing Unit (CPU). The instructions, which refer to specific operations of the processor, are defined by the Instruction Set Architecture, which typically includes four types of instructions: arithmetic, logic, data movement, and control flow. Before … Read more
Building Real-Time Operating Systems with C Language In modern embedded systems, a real-time operating system (RTOS) is a crucial component. It ensures that the system completes tasks within a specified time, suitable for time-critical applications such as industrial control, automotive electronics, and medical devices. This article will introduce how to build a simple real-time operating … Read more
HeliOS is an open-source, free embedded multitasking kernel designed for various low-power embedded devices. It offers a rich, well-documented API that allows fine control over the system and access to kernel services (system calls), enabling functionalities such as task management, scheduler management, inter-process communication, memory management, and device management, all while maintaining a minimal memory … Read more
This is a document I found online, where the author’s goal is to design a simple embedded operating system that implements a basic task scheduler.
