Algorithm-hardware mapping

Definition

Algorithm-hardware mapping is the process of aligning a specific algorithm's requirements with the characteristics and capabilities of the underlying hardware to achieve optimal performance and efficiency. This involves understanding both the algorithm’s computational needs and the hardware architecture, ensuring that the algorithm runs effectively on the chosen hardware platform. Successful mapping can lead to significant improvements in speed, energy consumption, and overall system functionality.
