4.2. Summary

In this chapter, we examined a group of pointers defined in the eCos system called virtual vectors.

For example, virtual vectors provide a mechanism for a ROM monitor to offer functionality for an application running from RAM. We then looked at the different configuration options for virtual vectors and the different communication channels.
