Bundled Instructions
Bundled Instructions are a very important design guide line to the EPIC
architecture. New EPIC architecture packs multiple instructions into
a very long instruction word for faster processing. This is called
LIW encoding, even though Intel doesn't care for the name much. Each
bundle also contains a flag that is set by the compiler to indicate which
instructions can be executed in parallel. The CPU can compile these
bundles in any order it chooses, and this causes the processor to stall
less often. Unlike CISC and RISC processors, now the CPU doesn't
have to scramble around, wasting time thinking about which instructions
it can run in parallel.
