Review Questions
How does algorithm-hardware mapping improve system performance?
Algorithm-hardware mapping improves system performance by ensuring that the algorithm is executed in a manner that leverages the strengths of the hardware architecture. By aligning computational requirements with hardware capabilities, systems can achieve faster execution times and reduced energy consumption. This alignment helps in utilizing resources more efficiently and can result in better overall system functionality.
What role do trade-offs play in the algorithm-hardware mapping process?
Trade-offs play a significant role in the algorithm-hardware mapping process as developers must balance various factors such as speed, energy efficiency, and memory usage. For instance, an algorithm optimized for speed might consume more power or require more memory than a less aggressive implementation. Understanding these trade-offs allows engineers to make informed decisions about which hardware platforms will best support their specific algorithms.
