3.1. Introduction

We consider multiprocessor systems on chips (MPSoCs) that will be designed and produced in deep submicron technologies (DSMs) with minimal features in the (100 to 25) nm range. Such systems will be designed using pre-existing components, such as processors, controllers, and memory arrays. The major design challenge will be to provide a functionally correct, reliable operation of the interacting components. The physical interconnections on chip will be a limiting factor for performance and possibly for energy consumption.

In this chapter, we address a methodology for the design of the interconnection among components that satisfies the needs for modular and robust design, under the constraints provided by the physical interconnect. ...
