AMD Processor

Advanced Micro Devices, Inc. (AMD) (NYSE: AMD) is an American multinational semiconductor company based in Sunnyvale, California, that develops computer processors and related technologies for commercial and consumer markets. Its main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and processor technologies for handheld devices, digital television, automobiles, game consoles, and other embedded systems applications.

AMD is the second-largest global supplier of microprocessors based on the x86 architecture after Intel Corporation, and the third-largest supplier of graphics processing units, behind Intel and Nvidia. It also owns 21 percent of Spansion, a supplier of non-volatile flash memory. In 2007, AMD ranked eleventh among semiconductor manufacturers in terms of revenue.

Advanced Micro Devices was founded on May 1, 1969, by a group of former executives from Fairchild Semiconductor, including Jerry Sanders III, Ed Turney, John Carey, Sven Simonsen, Jack Gifford and three members from Gifford's team, Frank Botte, Jim Giles, and Larry Stenger. The company began as a producer of logic chips, then entered the RAM chip business in 1975. That same year, it introduced a reverse-engineered clone of the Intel 8080 microprocessor. During this period, AMD also designed and produced a series of bit-slice processor elements (Am2900, Am29116, Am293xx) which were used in various minicomputer designs.

During this time, AMD attempted to embrace the perceived shift towards RISC with their own AMD 29K processor, and they attempted to diversify into graphics and audio devices as well as EPROM memory. It had some success in the mid-80s with the AMD7910 and AMD7911 "World Chip" FSK modem, one of the first multistandard devices that covered both Bell and CCITT tones at up to 1200 baud half duplex or 300/300 full duplex. While the AMD 29K survived as an embedded processor and AMD spinoff Spansion continues to make industry leading flash memory, AMD was not as successful with its other endeavors. AMD decided to switch gears and concentrate solely on Intel-compatible microprocessors and flash memory. This put them in direct competition with Intel for x86 compatible processors and their flash memory secondary markets.

AMD announced a merger with ATI Technologies on July 24, 2006. AMD paid $4.3 billion in cash and 58 million shares of its stock for a total of US$5.4 billion. The merger completed on October 25, 2006 and ATI is now part of AMD.

Problem Solving and Programming Logic

Computer Programs: The Power of Logic

A single program addresses a particular problem. When you write a program, you are solving a problem.

To solve a problem you must use your power of logic and develop an algorithm, or procedure, for solving the problem.

The algorithm is the finite set of step-by-step instructions that convert the input into the desired output, that is, solve the problem.

Structured Program Design: Divide and Conquer

Given a task, programmers were left on their own to create a solution any way they could.

Three major problems arose from this free-form method:
1.Long development time,
2.High maintenance cost, and
3.Low-quality software.

Structured programming stresses the systematic design and management of the program development process.

illustrates a common programming problem:

The printing of weekly payroll checks for hourly and commission employees. In the figure a structure chart is used to break the programming problem into a hierarchy of tasks. The most effective programs are designed to be written in modules, or independent task.

It is much easier to address a complex programming problem in small, more manageable modules than as one big task by using the principles of structured programming.

In structured programming, the logic of the program is addressed hierarchically in logical modules.

BY dividing the program into modules, the structured approach to programming reduces the complexity of the programming task.

Some programs are so complex that if taken as a single task.

Goals of structured programming :

Decrease program development time by increasing programmer productivity and reducing the
time needed to test and debug a program.

Decrease program maintenance costs by reducing errors and making program code easier to understand.

Improve the quality of software by providing programs with fewer errors.

Structured programming accomplishes these goals by incorporating these concepts:

1. Top-down design and use of modules.
   
2. Use of limited control structures (sequence, selection, and repetition).
   
3. Management control.

Top-down design starts with the major functions involved in a problem and divides them into subfunctions until the problem has been divided as much as possible.

Each unit is small enough to be programmed by an individual programmer in the required time frame.

This forces an examination of all aspects of a problem on one level before considering the next level.

A programmer is left with small groups, or modules, of processing instructions, which are easy to understand and code.

A program consists of a main logic module that controls the execution of the other modules in the program.

Working from the top down avoids solutions that deal with only part of a problem.

A program that uses a main logic module to control smaller modules is easier to read, test, and maintain.

In structured programming, modules ensure these qualities by:

-having only one entrance and one exit

-performing only one program function

-returning control to the module from which it was received

Programming In Perspective

What Is Computer Programming ?

Computer programming involves writing instructions and giving them to the computer so it can complete a task.

A computer program, or software, is a set of instructions written in a computer language, intended to be executed by a computer to perform a useful task.

The application packages such as word processors, spreadsheets, and database management systems are computer programs.

A programmer is an individual who translates the tasks that you want a computer to accomplish into a form the computer understands.
