multiple times on different data, like a vector instruction
2. A specific type of #1 that treats a normal register as a vector of
smaller operands, often seen in the media extensions to generalpurpose instruction sets.
What kind of parallelism does it exploit? DLP
1 c. What is VLIW? (Just stating what it stands for is not sufficient for full credit.) A VLIW (“very long instruction word”) instruction set packages multiple
instructions that can execute at the same time into a single word.
What kind of parallelism does it exploit? ILP
Does it do so statically (at compile time) or dynamically (at runtime)? Explain. Statically. The compiler is responsible for finding instructions that can
execute at the same time; that is, instructions that are independent and
which the machine has sufficient hardware to execute at once.
d. What are the sources of overhead for context switching (switching between threads...
