Executive Summary

Limits on applications and hardware technologies have put a stop to the frequency race during the 2000s. Designs now can be divided into homogeneous and heterogeneous ones. Homogeneous types are the easiest to use since most tool-chains and system software do not need too much of a rewrite. On the other end of the spectrum, there are the type two heterogeneous designs. These designs offer tremendous computational raw power, but at the cost of hardware features that might be necessary or even essential for certain types of system software and programming languages.
