1 word=64 bit=8 B 64 B=8 word machine cycle time=2 microseconds => 1 word is transferred from io buffer to memory by cpu in 2 microseconds => data preparation time by cpu 64 B data and io bandwidth is 1MBps so 64/10^6 seconds = 64 microseconds = transfer time by io device = time to dump data from io device to io buffer now in cycle stealing mode ...

First of all, the physical memory chips are no different between a 32 and 64 bit computer. The article talks about how the processor can reference (or address) the memory. In all modern architectures memory is byte-addressable, which means that every byte-sized memory cell has a number (its address), which the CPU uses to identify that cell. A simple 32 ...

Computer hardware is fundamentally parallel. Even a modern single CPU core is pipelined, meaning that at the same instant in time, one physical part of the CPU is initiating a fetch of an instruction, another is decoding a slightly earlier fetched instruction, another is calculating the new result of a slightly earlier decoded instruction, and another is ...
