All of the mentioned hardware techniques - duplication of resources, out-of-order issue, and renaming - can be used in a superscalar processor to enhance performance.

Duplication of resources involves replicating functional units or registers to allow for multiple instructions to be executed simultaneously. This helps improve parallelism and increase throughput.

Out-of-order issue involves executing instructions as soon as their dependent data becomes available, rather than strictly following program order. This helps to fill any idle slots in the pipeline and improve overall efficiency.

Renaming allows for multiple instances of the same register to be created without actually duplicating physical registers. This enables the processor to perform more operations in parallel and helps to avoid data dependencies.
