SA-1110 Microprocessor Development Board User’s Guide 3-3
Theory of Operation
As shown in Figure 3-2, the system partitioning allows the SA-1110 Development Board to be used
by itself as a minimal palm-size PC system. All device interfacing is implemented with in-system
programmable CPLDs and most system interface points are available on connectors suitable for
daughter boards or cables.
