What is an Embedded System?An embedded system employs a combination of hardware & software (a "computational engine") to perform a specific function; is part of a larger system that may not be a “computer works
Programming languages, such as embeddedC, Python andJavaScriptare among the many languages that can be used for embedded software development. Typically, a computer program known as acompileris used to transform thesource codewritten in a programming language into another computer language, such as t...
Also known as aphantom interruptorghost interrupt, aspurious interruptis a type of hardware interrupt for which no source can be found. These interrupts are difficult to identify if a system misbehaves. If the ISR does not account for the possibility of such interrupts, it may result in a s...
An embedded system is basically an electronic system that can be programmed or non-programmed to operate, organize, and perform single or multiple tasks based on the application. In the real time embedded systems, all the assembled units work together based on the program or set of rules or c...
What is kernel-level programming in an OS? Kernel-level programming involves writing software that interacts directly with the operating system's core functions (the kernel). This type of programming requires specialized knowledge and can be used to create device drivers, security software, and other...
such as superfluous and spurious interrupts, and unexpected task changes. It can be used with any (RT)OS which is instrumented to call SystemView event functions, but also in systems without an instrumented RTOS or without any RTOS at all, to analyze interrupt execution and to time user functi...

What is Interrupt Vector Table ( IVT) ? As its name suggests, it is a table that contains vectors. But what are vectors? In the physics world, the term vector means a dimension or direction. But in embedded programming, vector means memory address. Hence, a vector table is a table that...
In the FA and stage models, can an application check whether the system memory is sufficient to create a UIAbility and specify a process to run the UIAbility? What are the differences between the stage model and the FA model in intra-process object sharing? How do I call an installed...
routine (ISR) to handle the interrupt. The ISR is responsible for processing the interrupt and performing the necessary actions, such as reading data from a device or clearing an error condition. The ISR is designed to be as efficient as possible to minimize delays in the overall system ...
