Figure 8-17. Shared Bus Interface
The shared bus interface
is
probably the simplest and least expensive interface. How-
ever, the performance of the Inte1386 DX microprocessor may drop tremendously
because the Intel386 DX microprocessor must wait for the
82586
to complete its bus
operation before it can access the bus. This wait can
be
several hundred
eLK
cycles.
