Over the past several years, tremendous advances have
taken place in the design and performance of personal
computers. CPUs having faster processing speed and smaller
dimensions are being routinely manufactured for today's PCs.
For example, a high end Pentium 4 (P4) CPU for desktop PCs
has typical processing capability and speed up to 1,500 MIPS
and 2.4 GHz, respectively [l]. Typical P4 CPU dimensions
are 35 by 35 mm [I].
