First Round: 1. AND and OR gate using 2:1 Mux 2. Single line logic to check if a number is a power of 2 3. Working of in-order pipeline 4. Inputs to the program counter in an in-order pipeline 5. Working of a Branch Predictor and operations on it 6. Converting the in-order pipeline to an out-of-order pipeline 7. Register renaming and examples of memory disambiguation 8. Recursive function to find factorial of a number Second Round: 1. Project implementation details from resume 2.
