Part 3
Intelligent Medical Environments
The four chapters in Part 3 deal with medical machines based on the design philos-
ophy of medical processors, medical networks, artificial intelligence (AI) in the sci-
ence of medicine, and the deployment of nationally and internationally distributed
medical knowledge bases.
Chapter 9 contains the methodology that the computer scientists have very diligently
pursued in developing the architecture and composition of computers from its very
inception during the late 1940s to the newer multiple processor, multi-threaded
infused chip-based machines. As many as 64 processor VLSI chips are on the horizon.
Chapter 10 evolves and covers the functionality, role, and architectures of proces-
sors, bus structures of medical machines. The medical processor chip plays the
most crucial part. In conjunction with memories, I/O systems and global Internet
switches, the medical machines will play the role of networked computers in global
computing environments. Medical machines can be built many ways as computers
are built. Unfortunately, there are no centralized or standard committees to suggest
global medical protocols or interfaces. Hospitals and medical centers follow their
own style of conducting the medical practice as they fit. The local software
designers will write medical-ware macros and utilities as they see fit and the IT
engineers and network designers will simply adhere to the local directions rather
than following global medical standards.
Chapter 10 also summarizes the role of network and Internet technologies in the
medical field. As much as processor technology has evolved, network technology
has kept pace. As much as silicon and the high-k dielectric gate1 have contributed

2008. For the 45 nm technology node, high-k1 metal gate transistors have been introduced for the first
time in a high-volume manufacturing process [1]. The introduction of a high-k gate dielectric enabled a
0.7x reduction in Tox while reducing gate leakage 1000x for the PMOS and 25x for the NMOS transistors.
Dual-band edge work function metal gates were introduced, eliminating polysilicon gate depletion and pro-
viding compatibility with the high-k gate dielectric. In addition to the high-k1 metal gate, the 35 nm gate
length CMOS transistors have been integrated with a third generation of strained silicon and have demon-
strated the highest drive currents to date for both NMOS and PMOS. An SRAM cell size of 0.346 µ2 hasbeen achieved while using 193 nm dry lithography. High yield and reliability has been demonstrated on
multiple single-, dual-, quad-, and six-core microprocessors.
to the performance of processors, so much have fiber and erbium contributed to the
transport of data from one knowledge bank to another. Processing of data and
information that was the forte of CPUs has become merged with switching and gra-
phics in the newer more powerful processors of this decade. Network transmission
is much understood and deployed by the optical fiber and wireless cellular indus-
tries. Massive and global network switching is gradually being shifted in the
domain of optical switches and the communication processors in laptops, iPods,
and androids.
Chapter 11 tackles the issues in the design of medical processors. These processors
can only be in a genesis of computer processors and extensions of object proces-
sors. Medical processors deal with a rich array of medical sub-functions, utilities
and procedures. In addition, they contend with a rich variety of medical objects
(drugs, nurses, doctors, staff, patients, accountants, etc.) that are unique and distinc-
tive. If the medical functions are treated as “verb functions” and objects are treated
as “noun objects”, then the syntactic and semantic rules become complicated but
not insurmountable for compiler designers to handle. The rules and grammar of
“medical language” will thus be handled with a rich rules and grammar of the med-
ical compiler.
Chapter 12 revisits the medical machines from the perspective of practical proce-
dures in hospitals, medical centers, nursing homes, etc. If the procedures have a
distinct medical code, then this code drives the machine in an error proof, sophisti-
cated, efficient, and optimal fashion. The sub-procedures become the micro-code
that is assembled in view of the human and resource limitations of the hospital or
the medical center where the machine is located. The composition of the sub-
procedure is by itself a layer of the medical-ware and the compiler design.
