A computer contains many integrated circuits that enable it to perform its functions. Each chip incorporates from a few to many thousand logic gates, each an elementary circuit that performs Boolean and, or, exclusive or, or not operations on bits that are represented by electronic states. The CPU is usually the most complex integrated circuit in a PC.
Previous chapters have examined the 80x86 microprocessors’ instructions for moving data, performing arithmetic operations, branching, and utilizing subroutines. The 80x86 and other CPUs can also execute instructions that perform ...
