The Intel 8088 is an
Intel microprocessor based on the
8086, with 16-
bit registers and an 8-bit external
data bus. It can address up to 1
MB of
memory. The 8088 was introduced on
July 1,
1979, and was used in the original
IBM PC.The 8088 was targeted at economical systems by allowing the use of 8-bit designs. Large bus width circuit boards were still fairly expensive when it was released. The prefetch queue of the 8088 is 4 bytes, as opposed to the 8086's 6 bytes. The descendants of the 8088 include the
80188,
80186,
80286,
80386, and
80486 microprocessors which are still in use today. See the list below for a more complete list.
