e the data. Standard memory speeds have not progressed at same rate as processor speeds. As a result, the CPU can process data faster than the data can be fetched from memory or placed in memory. The Pentium motherboard operates at no more than 66MHz while CPUs can run at up to 266MHz. Consider that a 133MHz CPU cycles every 7ns while the access time for main memory is usually 70ns.Accessing each cell will incur the same circuit switching time overhead. This is the chip's access time. There will be address lines and also data lines to transfer data in and out of the cells to the CPU. A data transfer will either be a read operation (the cell's contents are copied on to the data bus) or a write operation (the contents of the data bus are copies into the cells). To instruct the chip, on which operation is required, it is fed read/write information on its control lines. If the CPU requires data from memory, it issues a read instruction along with the address to be read. To write data to memory, the CPU places the data on the data bus and issues a write instruction along with the address location.3. The term ALU stands for Arithmetic Logic Unit this carries out all the arithmetic and logical operations with in the CPU or Central Processing Unit.The term Register covers the areas of transient storage, which hold information keep track of instructions and retain the position and results of these operations. Each of the different registers has a specific purpose of what functions that it has to carry out they are located in the Execution Unit. There is a number of registers which carry out certain functions, e.g. memory address register, memory buffer register, stack pointer, program counter and the process status register.The term Control Circuit is used to control many of the computers other components such as the memory and the periheral devices. It has an interrupt unit that indicates the order in which particular operations use the CP...
