To provide some perspective on what we discussed in Part 1, Part 2, and Part 3, in this last part in this series, we will consider the important topic of characterization of applications and architectures.

To this end, trace-driven simulation is widely used to evaluate computer architectures and are useful in MPSoC design. Because we know more about the application code to be executed on an application-specific MPSoC design, we can use execution traces to refine the design, starting with capturing fairly general characteristics of the application and moving toward a more detailed study of the application running on a refined architectural model.

Because video applications are computationally intensive, we expect that more than one platform SoC will be necessary to build video systems for quite some time. For some relatively simple applications, it is possible to build a single platform that can support a wide variety of software.
