CPU cache

BRANCH PREDICTION: Image ref: http://www.xbitlabs.com/articles/cpu/display/haswell-uarch-idf_3.html#sect0 All the changes are consolidated in the core front-end. The execution pipeline remained the same, the L1 and L2 cache latencies also haven’t changed. However, Haswell boasts improved branch prediction, larger L2 TLB, larger buffers and Out-of-Order Window. EXECUTION UNITS: Previously, Intel…

be discerned and understood. Overclocking is the process that involves virtually increasing the speed/frequency of a processor. Cores and threads are the exact same thing, and they may be used interchangeably to refer to the physical portions of the CPU. We will be comparing and contrasting the Intel i5 3570k and the AMD FX-8320. This will cover the pros and cons that come along with buying these CPU’s. This will be broken down…

building a computer such as the motherboard, CPU, ram, hard drive type and much more. The reason its important to learn how to build a computer is for a couple of reasons, such as interest or wanting to save money on buying a pre-built one with parts you don’t want or need. Whatever the reason might be, there are a few things to know before starting a built. One of the most important things needed to build a computer is the CPU (Central Processing Unit). The CPU is part of a computer system…

this experiment, we found the latency incurred in measuring CPU cycles. This measurement of time overhead has to be subtracted from the forthcoming experiments. Methodology: We have used the RDTSC – RDTSCP instruction along with CPUID (serialize the instruction pipeline). This function fetches the count of CPU clock cycles. After taking the elapsed clock cycles between two successive calls to RDTSC instruction, we can divide it by the CPU clock frequency to get the absolute time. We have run…

· Memory: This is any computer component that has the ability to storing information or data temporary or permanently, e.g. Read And Write Memory (RAM) and Not Volatile Read And Write Memory (NVRAM). · CPU: This is the brain of the computer and is the central process unit, and it received command/instruction from the computer software and sends the instruction to the right hardware to execute the instruction, and also received the feedback from the hardware and forwards it to…

Cache is also a temporary storage memory. It is closer to the central processing unit and is even faster than the random access memory. Most of the instructions or data that are frequently used by the processor are stored in cache memory. When a processor uses certain data for the first process, a copy of the instructions is stored in the cache memory. If the processor needs the same instructions for another process, it checks in the cache memory first and if found data…

0 Ports located at top or sometimes the bottom of the computer case. Southbridge – This allows the CPU to communicate with SATA Connectors, USB Ports, Ethernet Ports, PCI Slots, PCI Express X1 Slots, and On-Board audio. The Southbridge is also referred to as the, Input/Output Controller Hub (ICH). Northbridge – This allows the CPU to communicate with the Graphics Card as well as the RAM. This…

Induction Assignment Task 1 CPU – The CPU of a computer stands for ‘Central Processing Unit’. Many people know this as the brain of the computer RAM – The RAM of a computer stands for ‘Random Access Memory’. The computers temporary memory is stored here. Hard Drive – The Hard Drive is used to store files and folders. Graphics Card – A Graphics Card is used by the computer to generate images onto your Screen (Both 2D and 3D) Power Supply – A Power Supply is used to power…

CPU known as Central Processing Unit also referred as Processor, Central Processor or microprocessor of the computer. It handles all the instructions from Hardware and Software. It is also called the brain of a computer as all the information is saved and stored in it. The CPU was first developed at Intel and they released 4004 processor. CPU chips are used in digital computers and often used to do the calculations. Processor is the engine of a computer; from this we can tell how fast the system…

Several expansion ports are incorporated into the motherboard which are used to house different adapter cards depending upon their connections or type. These expansion slots are detailed below: • Peripheral Component Interconnect (PCI) The PCI is used to attach various external hardware to the motherboard, these include: Network card, sound card, SATA card. It is important to note that a PCI cannot support a graphics card as the processing power required with recent graphics is too much for the…
