Introduction
CPU
Many people consider the CPU (Central Processing Unit) to be the brains of the computer. This is not true because, for the most part, the CPU cannot keep data stored inside it like a human brain. It is used to process much of the information needed by the computer, just like our brain thinks and processes information and gives orders to our other body parts.

ALU
Stands for (Arithmetic Logic Unit). An ALU is an integrated circuit within a CPU that performs arithmetic and logic operations. Arithmetic instructions include addition, subtraction, and shifting operations, while logic instructions include AND, OR, XOR, and NOT operations. CPU (Central Processing Unit)
CPU (Central Processing Unit) - otherwise known as a processor - is an electronic circuit that can execute computer programs. Both the miniaturization and standardization of CPUs have increased their presence far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to mobile phones.
The clock rate is one of the main characteristics of the CPU when performance is concerned. Clock rate is the fundamental rate in cycles per second (measured in hertz, kilohertz, megahertz or gigahertz) for the frequency of the clock in any synchronous circuit. A single clock cycle (typically shorter than a nanosecond in modern non-embedded microprocessors) toggles between a logical zero and a logical one state.
With any particular CPU, replacing the crystal with another crystal that oscillates with twice the frequency will generally make the CPU run with twice the performance. It will also make the CPU produce roughly twice the amount of…...

Cpu Analysis

...The CPU is a very important part of any computer. This part of the computer fetches the data, performs operations to the data and stores the data (the fetch execute cycle). The Workshop PC has an “AMD Athlon 64x2 4400+” processor these processors were first implemented into machines in 2005 meaning it has a possibility of being up to 6 years old. This processor has 2 cores meaning that the processor can receive 2 data strings at once rather than individually receiving them. Having a dual core processor is better than just a single core due to the fact that it can handle more data at once. But there are also newer quad core processors which would be much better than this processor. This processor has a core speed of 2294.4 MHZ this seems to be a reasonable speed for a processor to run at. It also has a multiplier of 11.5 having a multiplier of 11.5 means that there will be 11.5 cycles for every external clock cycle. The processor has a bus speed of 199.5MHz, the bus speed refers to how much data can travel across the bus at any one specific time. The speed of the bus can drastically affect the computers performance as the bus is essential for the transfer of data. The processor requires 1.350v of power to run it, this is relatively high compared to a lot of modern CPU’s that are available. The AMD Athlon has cache L1 data and L1 Inst of 2 x 64Kbytes and has L2 of 2 x 512Kbytes. The amount of cache memory is important as the cache memory stores data from the most used memory......

Cpu Storage

...The most common types of CPU’s on the market today are manufactured by Intel Advanced Micro Devices (AMD). Intel is the largest global supplier of microprocessors for the x86 architecture (PCs), and AMD is the second largest. AMD concentrates primarily on CPU’s, chipsets, and other microprocessors, but Intel delves into many other markets including networking technologies, motherboards, and much more. It is important to know some of the processors that each manufacturer develops so that you can different differentiate between the various types of PCs you can see in the field. The Pentium microprocessor is the CPU (central processing unit) for what are now possibly the widest-selling personal computers. Unlike previous CPUs that Intel made, the 486DX and Pentium chips included a floating-point unit (FPU) also know as a math coprocessor. Previous Intel CPUs did all their arithmetic using integers; programs that used floating-point numbers (non-integers like 2.5 or 3.14) needed to tell the chip how (for example) to divide them using integer arithmetic. The 486DX and Pentium chips have these instructions built into the chip, in their FPUs. This makes them much faster for intense numerical calculations, more complex, and more expensive. The problem for Intel is that all Pentiums manufactured until sometime this fall had errors in the on-chip FPU instructions for division. This caused the Pentium's FPU to incorrectly divide certain floating-point numbers. A mathematics professor by...

Cpu Scheduling

...CPU SCHEDULINGCPU scheduling in UNIX is designed to benefit interactive processes. Processes are given small CPU time slices by a priority algorithm that reduces to round-robin scheduling for CPU-bound jobs.The scheduler on UNIX system belongs to the general class of operating system schedulers known as round robin with multilevel feedback which means that the kernel allocates the CPU time to a process for small time slice, preempts a process that exceeds its time slice and feed it back into one of several priority queues. A process may need much iteration through the "feedback loop" before it finishes. When kernel does a context switch and restores the context of a process. The process resumes execution from the point where it had been suspended.Each process table entry contains a priority field. There is a process table for each process which contains a priority field for process scheduling. The priority of a process is lower if they have recently used the CPU and vice versa.The more CPU time a process accumulates, the lower (more positive) its priority becomes, and vice versa, so there is negative feedback in CPU scheduling and it is difficult for a single process to take all the CPU time. Process aging is employed to prevent starvation.Older UNIX systems used a 1-second quantum for the round- robin scheduling. 4.33SD reschedules processes every 0.1 second and recomputed priorities every second. The round-robin scheduling is accomplished by the -time-out mechanism, which......

Cpu Transistor Count in a Nutshell

...Since the 1960’s CPU transistor sizes have been steadily shrinking over time. Since the 1960’s the number of transistors on a Central Processing Unit have steadily increased from 2,300 on Intel’s first microprocessor the 4004, to more than 5 billion on Intel’s 62-Core Xeon Phi, released in 2012. Moore’s Law According to Moore’s Law, the number of transistors on an integrated circuit doubles every 18-24 months. Although Moore’s Law isn’t a law of the physical sciences, it is an observation by Gordon Moore made in the 1960’s. Transistor count is the most used method of measure for the complexity of integrated circuits. Intel’s Quad-Core Itanium Tukwila released in 2010 had 2 billion transistors on it’s die. As impressive as this is, Moore’s Law cannot continue indefinitely without modification. The reason for this is the laws of physics, that as the size of transistors shrinks and the number of transistors on a CPU die increases, transistors will eventually reach the limits of atomic sizes. At this size, silicon becomes unsuitable as a material to build integrated circuits out of, due to quantum tunneling and other factors. CPU die sizes will either have to get larger to fit more transistors (abet smaller transistors) and or increase the number of layers for each die. Moore’s Law is a model of exponential growth, and as such exponential growth is the fastest model of growth. Whether 100 billion or even 1 trillion transistors may fit on a single chip in the future,......

Cpu and Memory Installation

...Cpu And Memory Installation When installing the memory into the proper DIMM(dual inline memory module) slots you must make sure you have the right replacement specifications for your motherboard.You want to also remember the reason for installing memory is for more RAM(random access memory).Each motherboard requires a certain amount of memory and it wouldn’t be beneficial to add more than what is needed.However,the more memory you have installed, the faster the system.DIMMs can have chips on one side or on both sides and most address memory 64 bits a time. When you go to buy a DIMM, an ID that identifies the date the chip was manufactured will be stamped on it.Look for dates that are relatively close together and less than a year old. Try buying memory from a reliable source. “When setting up dual channeling, know that the pair of DIMMs in a channel must be equally matched in size, speed, and features, and it is recommended they come from the same manufacturer” (Andrews). If you happen to install memories with different speeds, the motherboard will run at the lesser of the two. “For a triple-channel installation, three DIMM slots must be populated with three matching DDR3 DIMMs” (Andrews).Most motherboards now are setup to allow dual channeling. Make sure to look at the motherboard documentation before installing. Most of the time the memory slots will be color coded for dual channeling. Dual channeling readies the DIMMs to receive 128 bits of information......

...video was about the components and functions that take place in the CPU. The video creates a visual of more or less where the components are, how they connect and what’s happening inside the CPU. The Information in this video was very specific and explained all the different elements of a CPU very well. I learned that there are a lot of things happening all simultaneously in the CPU. I also learned about the different components, their functions and placements of them inside. What I thought to be a little confusing was the details about Cache. All the different locations of the cache and different kinds of cache are too similar but I’m sure over time with more experience and hands on activities I will get more familiar with it. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CPUCentral Processing Unit | | | | NT1110- | | This video was about the components and functions that take place in the CPU.

Cpu Discription

...This part of the reading will examine the CPU, Buses, Controllers, and Main Memory. Other sections will examine input devices, output devices, and secondary memory. The Central Processing Unit (CPU) Figure 2: The Central Processing Unit The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions. All computers, large and small, must have a central processing unit. As Figure 2 shows, the central processing unit consists of two parts: The control unit and the arithmetic/logic unit. Each part has a specific function. Before we discuss the control unit and the arithmetic/logic unit in detail, we need to consider data storage and its relationship to the central processing unit. Computers use two types of storage: Primary storage and secondary storage. The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data. For this reason this part of the reading will discuss memory in the context of the central processing unit. Technically, however, memory is not part of the CPU. Recall that a computer's memory holds data only temporarily, at the time the computer is executing a program. Secondary storage holds permanent or semi-permanent data on some external magnetic or optical medium...

Thesis on Cpu

...According to the article”What is a Computer Virus” computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. Computer virus can attack computers in many ways and are often damaging to the computer. These viruses often spread without a persons knowledge about the virus and can be specially damaging to computers and expensive to those who own the computers to repair. Viruses can also affect program and the performance of the computer and cause severe harm. The main component in describing a virus is the viruses’ ability to replicate itself through computers or the internet. The first computer virus was created by Dr. Cohen, 26 yrs ago at the University of Southern California. Dr. Cohen realized that if a Trojan horse copied itself into other programs, then all those programs would be infected, and then everybody that ran any of those programs would get infected and so forth (Lee). From here, Dr. Cohen has since developed many ways to remove viruses and is one of the leading experts in that field. One of the most difficult things with viruses are they come in all different forms and are often disguised to the user. One type of virus is a direct action virus. According to the article “Different Types of Computer Viruses” on buzzle.com, the purpose of a direct action virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action......
