System resources

8.6.3.1

Currently allocated system resources

All system resources (hardware addresses, memory configuration, allocation of interrupts,
DMA channels) are assigned dynamically by the Windows OS, depending on the hardware
configuration, drivers and connected external devices. You can view the current
configuration of system resources or possible conflicts with the following operating systems:
Windows 10
Windows Embedded Standard
Windows 7 Ultimate
8.6.3.2

Allocation of system resources

The following tables and images describe the system resources for the delivery state of the
device.
PCIe interrupt lines
The interrupts are assigned to devices by BIOS. Only non-shared interrupts are available for
the first Ethernet interface.
This means that applications or realtime operating system expansions can operate these
devices exclusively and with high-performance without having to share the interrupt with
other devices.
