Introduction
Now that we have made a thorough and detailed study of the 8086 processor, it is time to learn
about the higher order versions of the x86 microprocessor family. In this and the next two chap-
ters, we will review the diff erences and enhancements of each of them.
Our fi rst case for study is the 80186/80188 processor. In terms of bus widths, they are
similar to the 8086/8088 processors, in the sense that both have an internal data bus width of
16 bits – but the 80186 has an external data bus width of 16 bits, while for the 80188, it is only
8 bits. Both have an address bus width of 20 bits. Having made clear this distinction, we will ...
