Chapter 11. Summary, Trends, and Conclusions

The shift from designing embedded systems with single-core processors to multi-core processors is motivated by the need for greater performance within reasonable power constraints. Systems with multiple processors are not new; what is new is the widespread availability of processors consisting of multiple cores that has been made possible by continued improvements in silicon manufacturing technology. In 1993, the most up-to-date Embedded Intel® Architecture processors were built using 0.8 micron process technology and incorporated 3 million transistors in one processor core. Fifteen years later, the state-of-the-art processors are built using 45-nm process technology and incorporate over 820 million ...
