Types of Instruction Scheduling
There are several types of instruction scheduling:
- Local (Basic Block) Scheduling: instructions can't move across basic block boundaries.
- Global scheduling: instructions can move across basic block boundaries.
- Modulo Scheduling: another name for software pipelining, which is a form of instruction scheduling that interleaves different iterations of a loop.
- Trace scheduling: the first practical approach for global scheduling, trace scheduling tries to optimize the control flow path that is executed most often.
- Superblock scheduling: a simplified form of trace scheduling which does not attempt to merge control flow paths at trace "side entrances". Instead, code can be implemented by more than one schedule, vastly simplifying the code generator.

Famous quotes containing the words types of, types and/or instruction:
“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“Everything from airplanes to kitchen blenders—and even chopsticks—comes with an instruction manual. Children, despite all their complexity, do not.”
—Lawrence Kutner (20th century)
