سلام
در این پاراگراف می خواستم بدونم مزایا و معایبEDF (یکی ار الگوریتم های بلادرنگ) چیه.
That is, EDF can guarantee that all deadlines are met provided that the total CPU utilization is not more than 100%. So, compared to fixed priority scheduling techniques like rate-monotonic scheduling, EDF can guarantee all the deadlines in the system at higher loading.
However, when the system is overloaded, the set of processes that will miss deadlines is largely unpredictable (it will be a function of the exact deadlines and time at which the overload occurs.) This is a considerable disadvantage to a real time systems designer. The algorithm is also difficult to implement in hardware and there is a tricky issue of representing deadlines in different ranges (deadlines must be rounded to finite amounts, typically a few bytes at most). Therefore EDF is not commonly found in industrial real-time computer systems.
و همچنین ترجمه ی این جمله:
A real time system responds in a (timley) predictable way to all individual unpredictableexternal stimuli arrivals
