You must be having a fair idea about an embedded system and you must be well aware about its key dynamics and functions. In this article we plan to share with you some characteristics which you should always monitor in your embedded system. Usually people focus only on 2 characteristics such as ROM and RAM usage; well yes these characteristics are important however these are not the only ones. Some other characteristics which hold prime importance in an embedded system have been discussed below:
The system timing must be monitored regularly by you and this is something many of the developers ignore all together today. As a professional developer you need to understand how your system will actually respond? Yes microprocessors can be utilized in this regard however they are also not an ultimate solution as they also do not fall in the category of a computing device.
As a professional developer try to understand the instruction execution order. Knowing the execution order helps you in knowing the fact that the system is jumping and in what particular order different interrupts and functions are getting executed. The modern day systems have become seriously complex hence as a developer you need to get the trace data pulled in order to see the execution of the code.
Monitoring of the code size is also one seriously important characteristic. It is a common perception that developers do monitor the code size however this perception is wrong. The code size depends very much on the compiler that has been utilized, the flags utilized and level of optimization. There are some cases where monitoring of the code becomes less significant as flash has become very cheap and it has become very easy for the vendors to switch various parts on the basis of code size.
RAM has become a seriously significant factor when it comes to development of embedded software. It is surely not uncommon for the microcontrollers to provide flash space that exceeds 100kB however only provides RAM worth 16KB. This actually means that RAM space is resting on premium. In a nutshell as a professional developer you need to implement and create software and also need to monitor your RAM spacing.
The Final Word
These were the five basic characteristics that often get ignored and that need to be frequently monitored by developers that are involved in embedded software. Yes the modern day systems are home to wonderful resources which mean that monitoring these characteristics sometimes seems unnecessary. The issue is that most of the issues that a developer encounters in embedded systems are related to these 5 characteristics in most of the cases.
