Computer architecture and organization (2)ResearchDr. Bassam KahhalehWaseem Arafeh20100014In this research we will discuss the techniques adopted by Intel designers to improve microprocessors. The focus will be on the Intel Core I7 CPU methods that allowed them to make advances in performance, CPU clock frequency, Quick Path interconnect speed, etc. Intel started marketing the i7 name in early 2008, before the "Core2" was launched. in use. Processors with I7 chip bring revolutionary changes to the CPU. MemoryThis element governs the memory I/O, previously it was located on a separate chip but now it is located inside the processor providing faster communication between the two components, this means Increased bandwidth and reduced memory latency. The memory channel supports three DDR3 memory channels; this means that you need to have a multiple of three dual in-line memory modules (DIMMs), which comprise a set of dynamic random access memories, then comes the memory frequency in which the memory DIMM can operate on various frequencies: 1333 MHz/1066 MHz/800 MHz, the frequency is proportional to the bandwidth and performance, so the higher the frequency the higher the bandwidth and performance but under the conditions:1. The motherboard must support this frequency.* The Core i7 requires the LGA1366 socket to work.2. There must be enough memory DIMMs populated per processor to equalize with the number of memory channels.* If there are 3 or fewer DIMMs populated for each processor, they will operate at 1333Mhz. If you add 1 to 3 more DIMMs, the original 3 and the added one will operate at the lower frequency of 1066 MHz. By considering both the memory channel and memory frequency, the memory capacity performance can be significantly increased. Intel QuickPath Interconnect...... half of paper ...... runs multiple operating systems side by side on the same computing hardware. Intel has added new features such as hardware-assisted page table management and direct I/O in Core i7 processors and its chipsets that allow the software to further improve its performance in virtualized environments. These improvements, combined with increases in memory bandwidth and processing performance, enable engineers and scientists to create more capable and complex virtualized systems for test, measurement and control. The Intel-based Core i7 processor family offers many new and improved features that benefit a wide variety of applications including test, measurement and control. Engineers and scientists can expect to see improvements in computing performance, as well as increases in memory and data throughput when comparing this microarchitecture to previous microarchitectures.
