Peripheral and Interface Components
Debug features
The RAMDevice implements a CADI MEMORY view. You can connect a CADI client to the
target and view the physical memory contents.
Verification and testing
The RAMDevice component has been tested as part of the VE example system using VE test
suites and by booting operating systems.
Performance
The RAMDevice component is not expected to significantly impact the performance of a PV
system.
Library dependencies
The RAMDevice component has no dependencies on external libraries.
5.4.43 SMSC_91C111 component
The SMSC_91C111 component implements a model of the SMSC 91C111 Ethernet controller.
The model provides the register interface of the SMSC part and can be configured to act as an
unconnected Ethernet port, or an Ethernet port connected to the host by an Ethernet bridge.
Information on how to install and configure the networking environment is described separately.
See Setting-up a network connection and configuring the networking environment for Microsoft
Windows on page 5-159.
Figure 5-63 shows a view of the component in System Canvas.
This component is written in C++.
