Real-Time Processing Systems
The processing of the uncontrolled stream of input data with little potential requirements for processing measured in seconds is referred to as real-time processing. To that effect, this paper shall highlight the essential characteristics of real-time system performance. It will also provide a real-time characteristic which is the most important and which may influence preferring one real-time system instead of another one.
There are several essential characteristics which are involved in real-time system performance. They include interrupt handling as well as distributed data systems. The former is a characteristic that denotes that a real-time system should respond to external stimuli in a time that is dictated by external factors. It is prudent to note that multiple interrupts are a common aspect, and the effect of such is that processing of data may be interrupted severally (Gumzej & Halang, 2010). The real operating system in performance should have a priority mechanism that allows these interrupts to be handled. The latter, on the other hand, deals with databases. Akin to other processing systems dealing with data, real-time systems are coupled with a management function for databases. Given that multitasking is commonplace in real-time system performance, and data is often performed in parallel, individual tasks can access their data easily without any impediments.
In a situation where I am to choose between different real-time processing systems, I would choose the interrupt handling characteristic. This is because it is my perception that this is the most critical aspect. In the sense that during interruptions, there is the interrupt latency, which is the maximum time that the system takes before it switches the task since there are several routine steps that must be followed and completed before the system shuts. An excellent real-time processing system is one that can be able to complete these tasks faster than another will be the best system. In that case, I will prefer a real-time processing system that has proper interrupt handling.
