All operations of the UART hardware are controlled by a clock signal which runs at a
multiple (say, 16) of the data rate - each data bit is as long as 16 clock pulses. The
receiver tests the state of the incoming signal on each clock pulse, looking for th
I386 and later processors contain a TLB as part of the cache memory where most recently used
page table entries are stored. Only if a page table entry needed is not present in the TLB, and thus
has to be reloaded from memory. If no reference had been made
Serial I/O Transfer
Todays computers operate on digital data in a parallel fashion. It handles and processes single-word data or
multiword data bits simultaneously rather than one bit at a time. Many peripherals handle data in a serial fashion.
Pipelining in Microprocessors
Modern microprocessors are structured and hence they contain many internal processing units.
Each unit performs a particular task. In real sense each of these processing units is actually a
special purpose microprocessor. The
