'''Central Processing Unit''' (CPU) is the main control mechanism of a [[computer]], containing control, logic, registers, and arithmetic and logic unit (ALU) as well as a memory interface. Some CPUs implement additional functionality, but often other capabilities are provided through peripheral processors that handle such things as I/O, Floating-point [[arithmetic]], and [[vector]] processing. All computers contain at least one CPU, but some contemporary computers contain over 1,000.

The purpose of a CPU is to execute programs. Programs are a series of numeric values, where each value indicates a specific operation. Each value is referred to as an '''instruction'''. These values are known as [[machine code]]. All of the instructions that can be executed by a CPU are collectively known as the CPU's '''instruction set'''. Different CPU models usually implement completely different instruction sets, so that programs written for one CPU will not execute on a different one. Writing programs in machine code is difficult, so programs called '''assemblers''' were written to translate mnemonics into machine code, thus increasing the speed of writing, and the reliability of, programs. Since the 1960s, most programs have been written using a [[Programming Language]], which are even easier to use than an assembler.

A microprocessor is a '''any''' processor implemented on a single integrated circuit, however most microprocessors are CPUs. The most common microprocessors used in general-purpose computers are from [[Intel]].

'''Source code''' is the statements and declarations, usually in human readable form, the specifies a computer program. Knowledge of programming is usually necessary in order to read and understand source code in a program.

== Example ==
The following is an example of a C program that when compiled and executed prints the words "Hello world" to the screen. A "C" [[compiler]] and [[linker]] is necessary to compile the program and turn it into an executable. Historically, an assembler is also needed, but newer compilers often integrate the assembler and linker functions together.

HitTheHive: FPGA belongs in electrical engineering category; not computer science

An '''FPGA''' is a '''F'''ield '''P'''rogrammable '''G'''ate '''A'''rray, a type of [[gate array]] that is programmable after assembly. Usually, FPGAs are also reprogrammable, meaning they can be upgraded.

== Architecture ==
Most FPGAs have combinatorial blocks followed by sequential elements. A combinatorial block can be used to implement boolean logic such as AND, OR, NAND, NOR, and other combinations. A sequential element is a flip flop, a single bit memory, most often a D flip-flop. Some FPGAs also have more complex memories organized as RAM. The most complex FPGAs have processors, multi-giga bit tranceivers, DSP and other high-order functions built in.
== Applications ==
FPGAs can be used for a variety of embedded system applications, from specialized network packet processors (e.g., VoIP firewalls) to systems on a chip (processor, memory, peripheral devices). For example, Internet core routers often use FPGAs on media cards for packet processing and routing functions.

Machine code

HitTheHive: Machine code article

'''Machine code''' is a sequence of binary numbers that control a centeral processing unit([[CPU]]). On very early computers, machine code was the language used to program computers. In modern times, however, [[computer software]] is usually written in a higher level language such as C, Java, Fortran, and assembly language.

For many CPUs, Machine code is generated from assembly langauge via an assembler, or sometimes directly from higher level languages such as C.
