Flavors of the Von Neumann bottle neck, an issue that could be likened to Boston traffic congestion, one of the first contestants, can be found everywhere in the realm of technology. The system bus the other communication highway has historically been ‘the weakest link’, rather a source of bottlenecks, traffic jams, in the hardware of a computer. The great battle of one-ups-man-ship between top chip companies has led to crashing prices and amazing increases in CPU speeds, but CPUs share communication hardware with slower devices and as a result CPUs are often waiting around for the data and instructions they need to do what they need to do.
Boston’s ‘Big Dig’ construction project widened existing highways: three and four lanes to five and six lanes, added alternate routes: tunnels, expanded the airport and railroads: faster channels and direct routes. Since the original ‘system bus’, “You are the weakest link, goodbye”, all these methodologies have been implemented, but each has its limitations, sacrifices. Solutions to flavors of this problem since the original ‘system bus’ include a front and rear side bus architecture, caching, and dedicated routes have been added: direct memory access technologies. Technology again faces the latest incarnation of this problem.
With multi-processor and multi-core architectures the CPU is not only competing with primary memory, secondary memory, input devices, and output devices, they are also competing with other CPUs or cores whichever the case, all trying to get their point across! The solutions offered today are coined QuickPath by Intel, and HyperTransport by AMD, a detailed description of each is explained below. HyperTransport HyperTransport was developed due to the need to support higher speed processors and memories. The technology was influenced by the need for PCI (Peripheral Component Interconnect) compatibility with a low cost implementation (Hyper 5).
The Essay on Bluetooth Technology
Bluetooth Technology Today computer technologies are rapidly developing, which allows millions of people around the globe to work faster and more conveniently. Bluetooth is the wireless networking initiative that is led by the worlds most advancing information technologies companies such as Ericsson, Intel, Nokia, IBM, Toshiba, Lucent and others. The creation of Bluetooth is a remarkable advance ...
