| 11. | Results from the execution units and loads are not written to the register file.
|
| 12. | Contemporary VLIWs usually have four to eight main execution units.
|
| 13. | Thus, there is an upper bound on the usefulness of adding more parallel execution units.
|
| 14. | In each clock cycle, up to five micro-ops can be dispatched to five execution units.
|
| 15. | Together, these elements form an " execution unit ".
|
| 16. | To get better CPI values with pipelining, there must be at least 2 execution units.
|
| 17. | Most modern processors also have multiple execution units.
|
| 18. | Superscalar processors differ from multi-core processors in that the several execution units are not entire processors.
|
| 19. | The dispatch unit issues the instructions to the appropriate execution units depending on operand and resource availability.
|
| 20. | It is common for modern CPUs to have multiple parallel execution units, referred to as superscalar designs.
