2 cards from this section. Quick, good the night before a test.
What does a superscalar processor do?
Think about how many tasks it can handle at once.
Define issue width.
Consider what happens in a single tick of a clock.
What is a characteristic of superscalar processors?
Think about how they differ from scalar processors.
True or False: Superscalar processors can execute multiple instructions simultaneously.
Recall the definition of superscalar processors.
Assuming a superscalar processor with an issue width of 4, calculate how many instructions could theoretically be executed in a 10-cycle window if all conditions for parallel execution are met.
Multiply the issue width by the number of cycles.
Design a simple scheduling algorithm for a theoretical superscalar processor that enhances utilization. Explain how you would handle instruction dependencies.
Consider algorithms like FIFO or priority scheduling and adapt them for instruction dependencies.
