WebControl hazard occurs whenever the pipeline makes incorrect branch prediction decisions, resulting in instructions entering the pipeline that must be discarded. A control hazard is often referred to as a branch hazard. In this article, we will dive deeper into Control Hazards according to the GATE Syllabus for (Computer Science Engineering) CSE.

WebData Hazard in Pipelining. To be precise I am here for RAW hazard. Consider a 5 stage pipeline . In case of I 4 − I 1 dependency , I am not sure if it is an R A W hazard as I 4 does not depends on value of R 1 that I 1 gives. and even if it fetches it ,it still be a wrong value as per the instruction sequence as I 2 is modifying it. So , is I ...
