dissipated as heat, and for radio frequency components the heat dissipation is equal
to the power consumption minus the output radio signal. The NTRS/ITRS roadmaps
for power dissipation of high-performance processors are shown in Figure 1.6. Note
that (up to 2003) the ITRS roadmap predicted a continuous rise in chip power dissi-
pation while the 2005 and 2007 roadmaps capped the heat dissipation at 200 W due
to constraints in the current “system level cooling and test” technologies rather than
in the “packaging” [3]. This shows the important role that innovative, cost-effective,
and high-per ...
