Subject: Regarding branch delay instructions in R4000
Date: Fri, 19 Dec 2003 06:01:27 +0000 (GMT)	[thread overview]
Message-ID: <20031219060127.90257.qmail@web10107.mail.yahoo.com> (raw)

Hi All,

    If this is not a right forum to ask this Question,

please redirect me to the appropriate one...
    Since R4000 is using the 8 stage pipeline, three
instructions are already entered into the pipeline
when the branch instruction is executed. Out of these
three instructions, the first instruction will be 
executed for sure.

My question is:
    What happens to the other two instruction that are
in the delay slots? are they nullified?
    Could anyone please shed some light on this.

Thanks much,
-karthi
