QP™/C Real-Time Embedded Framework (RTEF) is a lightweight implementation tailored for real-time embedded (RTE) systems based on an active object computing model. QP serves as both a software infrastructure for building applications composed of active objects (actors) and a runtime environment for executing active objects in a deterministic manner. Moreover, the QP framework supports hierarchical … Read more
Explanation: 1. The Bootloader handles the initial boot sequence on hardware before the operating system takes over. For example, U-boot is often used as the boot loader in embedded systems before starting embedded operating systems like Linux or FreeBSD. MCUBoot is also a bootloader, but it targets IoT, referring here to systems with limited memory … Read more

Embedding concurrency means multi-threading or multi-tasking, which is basically implemented using systems like Linux or RTOS. In RTOS, task scheduling mainly includes preemptive and time-slicing scheduling, and the specific differences will not be detailed here. This chapter contains some terms related to concurrency, such as concurrency, criticality, resources, deadlocks, etc. It is best to read … Read more
Analysis of HarmonyOS Architecture The overall structure of HarmonyOS adopts a layered design, from bottom to top: Kernel Layer: Multi-core, selecting the appropriate OS kernel for different resource-constrained devices, masking multi-core differences. System Service Layer: Core capabilities, providing services to application layer programs through the framework layer. Application Framework Layer: Multi-language framework Application Layer: System … Read more
This series begins with a discussion on software design, particularly focusing on design patterns in object-oriented programming, which you may have encountered in your own development or seen in others’ code. When your codebase becomes sufficiently large, you may find maintenance becomes a daunting task, where a small change can have wide-reaching consequences. At this … Read more
