14.4. Optimal CPU Configurations and Interconnections

For the ever increasing set of media-processing applications, improving the performance of the execution of a single instruction stream often results in only a limited overall gain in the system performance. Intuition and experiments suggest that for these applications, much better performance can be achieved by employing multiple processors that share the burden of controlling the necessary real-time and non-real-time tasks.

14.4.1. Monolithic CPUs

In addition to integrating various audio, video, and peripheral interface units, an emerging trend for multimedia SoCs is to muster enough processing power by utilizing multiple CPU cores. In fact, quite a few of the currently available ICs already ...
