Branch Prediction Logic

Branch Prediction Logic. UQ : Explain how the flushing of pipeline can be minimised in Pentium Architecture. Flushing of pipeline problem. Performance gain through pipelining can be reduced by the presence of program transfer instructions (such as JMP,CALL,RET and conditional jumps).
