Answer / kwrtos
A real-time system is the system that is capable of
accomplishing its given tasks within a defined period of
time which must be fully acceptable within the scope of the
definition of successful operations to the system. For
instance, if a TV signal-handling system must successfully
finish all its tasks within 16 milliseconds to guarantee a
flick-free video, it has to operate as a real-time system
with respect to the real-time constraints defined as 16ms.

what are the rules u follow when u r writing critical section of code?
I have been working on one thread which manage and control a couple of circular buffers. It has api for other thread to access. As the thread grows bigger and bigger, I split it as 3 to 4 threads which need to share common buffers, and also their api could be used by other threads, (not these three threads). Inside api, I also allow other threads to access these three threads' common buffers(more than one buffer). SO I have to use mutex to avoid race condition . But I found mutex will be everwhere in all the threads when they update the common buffer. I am wondering whether I could reduce mutex usage(more mutex will hure my system performance). any ideas for how to reduce mutex usage meanwhile to avoid race condition. Thanks
