I have the book
The reason for the growing interest in networks on chips (NoCs) can be
explained by looking at the evolution of integrated circuit technology and
at the ever-increasing requirements on electronic systems. The integrated
microprocessor has been a landmark in the evolution of computing technology.
Whereas it took monstrous efforts to be completed, it appears now
as a simple object to us. Indeed, the microprocessor involved the connection
of a computational engine to a layered memory system, and this
was achieved using busses. In the last decade, the frontiers of integrated
circuit design opened widely. On one side, complex application-specific
integrated circuits (ASICs) were designed to address-specific applications,
for example mobile telephony. These systems required multiprocessing
over heterogeneous functional units, thus requiring efficient on-chip
communication. On another side, multiprocessing platforms were developed
to address high-performance computation, such as image rendering.
Examples are Sony's emotion engine [25] and IBM's cell chip [26],
where on-chip communication efficiency is key to the overall system
performance. |
