Design Principles

"Optimize real-time embedded system performance by partitioning computationally intensive tasks to dedicated hardware accelerators."

This approach is crucial for embedded systems that require high-speed data processing and immediate decision-making, such as in autonomous vehicles or advanced driver-assistance systems. By offloading computationally intensive tasks to dedicated hardware, overall system efficiency and responsiveness are significantly improved.

What This Means for Your Design

To make a computer system that recognizes traffic signs work really fast, we can use a special chip (FPGA) to do some of the hard math really quickly, while the main computer brain (CPU) does the rest.
