1) "Issue group" is a set of instructions which can
be issued to different execution units at same time so
that many execution units can be executed parallely.
Can any one tell any sourse where I can get the
information such as which set of instructions are
called as an issue group(in case of pentium 4
2) Compilers exploit such a feature by reodering
But Pentium 4 processor reoders instructions to do
the same thing.
So reordering by compilers is unnessecary.
Am I right????????????
3)How many instructions does Pentium 4 processor can
look insatantly to reorder instructions?
