CH5 MICROPROCESSOR MCGRAW CONNECT

multicore processor

A new type of chip that provides two or more separate and independent CPUs.

Microprocessor chips

chip processing capacities are often expressed in word sizes A WORD is the number of bits (such as 32 or 64 ) that can be accessed at one time by the CPU the more bits in a word, the more data a computer can process at one time. eight bits group together to form a byte A 32-BIT-WORD computer can access 4 bytes at a time A 64-BIT-WORD computer can be access 8 bytes at a time. Therefore the computer designed to process 60 bit words has greater processing capacity. The factors affect a computers processing capability including how fast it can process data and instructions

Logical operation

Comparing two pieces of data to see whether one is equal to (=), less than (<), or greater than (>) the other.

Arithmetic Logic Unit (ALU) The part of the CPU that performs arithmetic and logical operations.

Performs two types of operation 1)arithmetic 2)logical

Select all the components of the CPU.

1) Control unit 2)Arithmetic Logic Unit

clock speed

Also called clock rate. It is measured in gigahertz, or billions of beats per second. The faster the clock speed, the faster the computer can process information and execute instructions.

Arithmetic operation Fundamental math operations: addition, subtraction, multiplication, and division.

Are the fundamental math operations addition subtraction multiplication and division

However is the potential for personal computers to run very large complex programs that previously require expensive and specialized hardware

For multicore processors to be used efficiently computers must understand how to divide task in two parts that can be distributed across each core and operations called parallel processing operating system such as windows 10 and Mike 0S Mojave supports parallel processing software developers use this technology for a wide range of applications from scientific programs to sophisticated computer games

Coprocessor Specialized processing chip designed to improve specific computer operations, such as the graphics coprocessor.

For one of the more popular specialty processors are specialty chips designed to improve specific computing operations for an example to support fast processing or virtual environment a standard feature in gaming computer is a graphics coprocessor known as a GPU

Specialty Processors

In addition to microprocessor chips a variety of more specialized processing chips have been developed and are widely used For an example many cars had more than 100 separate specialty processors to control nearly everything from Filo efficiency to satellite entertainment and tracking system

Microprocessor The central processing unit (CPU) of a personal computer controls and manipulates data to produce information. The microprocessor is contained on a single integrated circuit chip and is the brains of the system. Also known as a processor.

In most personal computer systems the central processing unit CPU or processor is contain on a single chip called the microprocessor

THE processing speed of a microprocessor IS TYPICALLY PRESENTED BY ITS CLOCK SPEED WHICH IS RELATED TO THE NUMBER OF TIMES THE CPU CAN FETCH AND PROCESS DATA OR INSTRUCTIONS IN A SECOND

Older personal computers typically process data and instructions in millionths of a second or microseconds newer personal computers are much faster and processed data and instructions in the billionths of a second or nanoseconds Super computers by contrast operate at speed measured in picoseconds -- 1,000 times as fast as personal computers. In the near future we can expect processor speed to be 1,000 times faster than the operating at speeds measuring in femtoseconds Logically the hire a microprocessor'S Clock speed the faster than microprocessor HOWEVER some processors can be handled multiple instructions per psycho or tick of the clock that means the clock speed comparison can only be made between processors that work in the same way

Control unit Section of the CPU that tells the rest of the computer how to carry out program instructions.

Tells the rest of the computer system how to carry out a program's instructions it directs the movement other electronic signals between memory which Temporarily holds data instructions and processing information and the arithmetic-logic unit it's also directs these control signals between the CPU and input and output devices

Microprocessor The central processing unit (CPU) of a personal computer controls and manipulates data to produce information. The microprocessor is contained on a single integrated circuit chip and is the brains of the system. Also known as a processor.

The microprocessor is the brains of the computer system it has two basic components 1) Control unit 2)arithmetic- logic unit

WORD A Blank______ is the number of bits that can be accessed at one time by the CPU.

The number of bits (such as 16, 32, or 64) that can be accessed at one time by the CPU.

Central Processing Unit (CPU)

The part of the computer that holds data and program instructions for processing the data. The CPU consists of the control unit and the arithmetic-logic unit. In a personal computer, the CPU is on a single electronic component called a microprocessor chip.

Processor The central processing unit is also called the Blank______.

The part of the computer that holds data and program instructions for processing the data. The CPU consists of the control unit and the arithmetic-logic unit. In a personal computer, the CPU is on a single electronic component called a microprocessor chip.

graphics coprocessor/graphics processing unit (GPU) Designed to handle requirements related to displaying and manipulating 2D and 3D graphic images. A Blank______ is an example of a specialty processor.

These processors are designed to handle a variety of specialIZED tasks such as displaying 3D images and encrypting data MOST cell phones and tablets have specialty processors to efficiently show and store videos

At one time personal computers were limited by microprocessors that could support a single CPU that controlled operations.

these computers were limited to processing one program at a time now many personal computers have a multiple core processors that can be provided two or more separated independent CPUs For an example a quad-core processor could have one core computing a complex EXCEL specialty a second core creating reporting using WORD a THIRD core locating a recording using access and a FOURTH core running in multimedia presentation all at the same time More significantly
