CPU
processor
(CPU, processor) The part of a
computer which controls all the other parts. Designs vary
widely but the CPU generally consists of the control unit,
the arithmetic and logic unit (ALU), registers, temporary
buffers and various other logic.
The control unit fetches instructions from memory and
decodes them to produce signals which control the other parts
of the computer. These signals cause it to transfer data
between memory and ALU or to activate peripherals to perform
input or output.
Various types of memory, including cache, RAM and ROM,
are often considered to be part of the CPU, particularly in
modern microprocessors where a single integrated circuit
may contain one or more processors as well as any or all of
the above types of memory. The CPU, and any of these
components that are in separate chips, are usually all located
on the same printed circuit board, known as the
motherboard. This in turn is located in the system unit
(sometimes incorrectly referred to as the "CPU").
A parallel computer has several CPUs which may share other
resources such as memory and peripherals.
The term "processor" has to some extent replaced "CPU", though
RAM and ROM are not logically part of the processor.

upper case names to distinguish them from C identifiers. This
symbol can be used later in the input, as in
char input_buffer[BUFFER_SIZE];
This use of cpp to name constants, rather than writing these
magic numbers inline, makes a program easier to read and

macro preprocessor
(foldoc) | preprocessor
macro preprocessor
A program that transforms input data in some way
before it is read by the main program. In the case of a
compiler, the input is source code. The main advantage of
using a preprocessor is that it is possible to change the
specification of the input data without changing the main
program. The separation can also help to make the system's
overall behaviour easier to understand. The disadvantage is
that performance may be reduced by the extra input and output
performed between the two programs.
For example, the C preprocessor, cpp, handles textual
macro substitution (it acts as a "macro preprocessor"),
conditional compilation and inclusion of other files.
A preprocessor may be used to transform a program into a
simpler language, e.g. to transform C++ into C.

microprocessor
(foldoc) | microprocessor
micro
(Or "micro") A computer whose entire CPU is
contained on one (or a small number of) integrated circuits.
The important characteristics of a microprocessor are the
widths of its internal and external address bus and {data
bus} (and instruction), its clock rate and its {instruction
set}. Processors are also often classified as either RISC
or CISC.
The first commercial microprocessor was the Intel 4004 which
appeared in 1971. This was the CPU member of a set of four
LSI integrated circuits called the MCS-4, which was
originally designed for use in a calculator but was marketed
as "programmable controller for logic replacement". The 4004
is referred to as a 4-bit microprocessor since it processed
only 4 bits of data at a time. This very short word size is
due mainly to the limitations imposed by the maximum
integrated circuit density then achievable.
As integrated circuit densities increased with the rapid
development of integrated circuit manufacturing technology,
the power and performance of the microprocessors also
increased. This is reflected in the increase in the CPU word
size to 4, 8, 16, and by mid-1980s, 32 bits. The smaller
microprocessors have relatively simple instruction sets,
e.g., no floating point instructions, but they are
nevertheless suitable as controllers for a very wide range of
applications such as car engines and microwave ovens.
The Intel 4004 was followed with, among others the 4040,
8008, 8080, 8086, 80186, 80286, 80386, 486 and
Pentium. Other families include the Motorola 6800 and
680x0 families, National Semiconductor 16000 and {National
Semiconductor 32000}, SPARC, ARM, MIPS, Zilog Z8000,
PowerPC and the Inmos Transputer family.
The larger, more recent microprocessors families have
gradually acquired most of the features of large computers.
As the microprocessor industry has matured, several families
of microprocessors have evolved into de facto industrial
standards with multiple manufacturers and numerous "support"
chips including RAM, ROM, I/O controllers etc.
A single chip microprocessor may include other components such
as memory (RAM, ROM, PROM), memory management,
caches, floating-point unit, input/output ports and
timers. Such devices are also known as microcontrollers.
The one-chip microcomputer is in many respects, a landmark
development in computer technology because it reduces the
computer to a small, inexpensive, and easily replaceable
design component.
Microcomputers have given rise to a new class of
general-purpose machines called personal computers. These
are small low cost computers that are designed to sit on an
ordinary office desk or to be portable and fuelled the
computer boom of the late 1980s. The most widespread example
is the also IBM PC, based on microprocessors from {Intel
Corporation}. Apple Computers, Inc. have also produced a
range of personal computers, as have several other companies.

microprocessor without interlocked pipeline stages
(foldoc) | Microprocessor without Interlocked Pipeline Stages
MIPS project
(MIPS) A project at Stanford University intended
to simplify processor design by eliminating hardware
interlocks between the five pipeline stages. This means
that only single execution cycle instructions can access the
thirty two 32-bit general registers, so that the compiler
can schedule them to avoid conflicts. This also means that
LOAD/STORE and branch instructions have a one-cycle delay to
account for. However, because of the importance of multiply
and divide instructions, a special HI/LO pair of
multiply/divide registers exist which do have hardware
interlocks, since these take several cycles to execute and
complicate instruction scheduling.
The project eventually lead to the commercial MIPS R2000
processor.

multiprocessor
(foldoc) | parallel processing
multiprocessing
multiprocessor
parallel
parallel computing
(Or "multiprocessing") The simultaneous use of more
than one computer to solve a problem. There are many
different kinds of parallel computer (or "parallel
processor"). They are distinguished by the kind of
interconnection between processors (known as "processing
elements" or PEs) and between processors and memory. {Flynn's
taxonomy} also classifies parallel (and serial) computers
according to whether all processors execute the same
instructions at the same time ("{single instruction/multiple
data}" - SIMD) or each processor executes different
instructions ("multiple instruction/multiple data" - MIMD).
The processors may either communicate in order to be able to
cooperate in solving a problem or they may run completely
independently, possibly under the control of another processor
which distributes work to the others and collects results from
them (a "processor farm"). The difficulty of cooperative
problem solving is aptly demonstrated by the following dubious
reasoning:
If it takes one man one minute to dig a post-hole
then sixty men can dig it in one second.
Amdahl's Law states this more formally.
Processors communicate via some kind of network or bus or a
combination of both. Memory may be either shared memory
(all processors have equal access to all memory) or private
(each processor has its own memory - "distributed memory")
or a combination of both.
Many different software systems have been designed for
programming parallel computers, both at the operating system
and programming language level. These systems must provide
mechanisms for partitioning the overall problem into separate
tasks and allocating tasks to processors. Such mechanisms may
provide either implicit parallelism - the system (the
compiler or some other program) partitions the problem and
allocates tasks to processors automatically or {explicit
parallelism} where the programmer must annotate his program to
show how it is to be partitioned. It is also usual to provide
synchronisation primitives such as semaphores and monitors
to allow processes to share resources without conflict.
Load balancing attempts to keep all processors busy by
allocating new tasks, or by moving existing tasks between
processors, according to some algorithm.
Communication between tasks may be either via shared memory
or message passing. Either may be implemented in terms of
the other and in fact, at the lowest level, shared memory uses
message passing since the address and data signals which flow
between processor and memory may be considered as messages.
The terms "parallel processing" and "multiprocessing" imply
multiple processors working on one task whereas "{concurrent
processing}" and "multitasking" imply a single processor
sharing its time between several tasks.

optical signal processor
(foldoc) | optical computing
Optical Signal Processor
OSP
(Or "Optical Signal Processing") Operating on data
represented using electromagnetic radiation, e.g. visible
light, instead of the electrical signals used in a
conventional electronic digital computer.
Electronic digital computers are built from transistors.
These form components that store data and logic gates that
perform the low-level Boolean operations such as AND, OR
and NOT that are the basis of all digital computation.
The optical equivalent requires material with a non-linear
refractive index such that light beams can interact with each
other to perform the same Boolean operations.
Though the photons that carry optical signals offer some
theoretical advantages over the electrons that carry
electronic signals, there are many practical problems that
would have to be overcome before optical computing could
compete in terms of cost, power and speed.

scalable processor architecture
(foldoc) | Scalable Processor ARChitecture
(SPARC) An instruction set architecture designed
by Sun Microsystems for their own use in 1985. Sun was a
maker of 680x0-based Unix workstations. Research
versions of RISC processors had promised a major step
forward in speed but existing manufacturers were slow to
introduce a RISC type processor, so Sun went ahead and
developed its own, based on the {University of California at
Berkley}'s RISC I and RISC II 1980-2. In keeping with
their open philosophy, they licenced it to other companies,
rather than manufacture it themselves. The evolution and
standardisation of SPARC is now directed by the non-profit
consortium SPARC International, Inc.
SPARC was not the first RISC processor. The AMD 29000
came before it, as did the MIPS R2000 (based on Stanford's
design) and Hewlett-Packard Precision Architecture CPU,
among others. The SPARC design was radical at the time, even
omitting multiple cycle multiply and divide instructions (like
a few others), while most RISC CPUs are more conventional.
SPARC implementations usually contain 128 or 144 registers,
(CISC designs typically had 16 or less). At each time 32
registers are available - 8 are global, the rest are allocated
in a "window" from a stack of registers. The window is moved
16 registers down the stack during a function call, so that
the upper and lower 8 registers are shared between functions,
to pass and return values, and 8 are local. The window is
moved up on return, so registers are loaded or saved only at
the top or bottom of the register stack. This allows
functions to be called in as little as 1 cycle. Like some
other RISC processors, reading global register zero always
returns zero and writing it has no effect. SPARC is
pipelined for performance, and like previous processors, a
dedicated condition code register holds comparison results.
SPARC is "scalable" mainly because the register stack can be
expanded (up to 512, or 32 windows), to reduce loads and saves
between functions, or scaled down to reduce interrupt or
context switch time, when the entire register set has to be
saved. Function calls are usually much more frequent, so the
large register set is usually a plus.
SPARC is not a chip, but a specification, and so there are
various implementations of it. It has undergone revisions,
and now has multiply and divide instructions. Most versions
are 32 bits, but there are designs for 64-bit and
superscalar versions. SPARC was submitted to the IEEE
society to be considered for the P1754 microprocessor
standard.
SPARC(R) is a registered trademark of SPARC International,
Inc. in the United States and other countries.

symmetric multiprocessor
(SMP) Two or more similar processors connected

This is in contrast to the "compute server" kind of
parallel processor where a front-end processor handles all
I/O to disks, terminals and local area network etc.
The processors are treated more or less equally, with
application programs able to run on any or perhaps all
processors in the system, interchangeably, at the operating
system's discretion. Simple MP usually involves assigning
each processor to a fixed task (such as managing the file
system), reserving the single main CPU for general tasks.
OS/2 currently supports so-called HMP (Hybrid
Multiprocessing), which provides some elements of symmetric
multiprocessing, using add-on IBM software called MP/2. OS/2
