1. Programmable mapping done by the Raven ASIC.
2. Programmable mapping via the four PCI Slave Images in the
Universe ASIC.
3. Programmable mapping via the Special Slave Image (SLSI) in the
Universe ASIC.
VMEbus Slave Map
The four programmable VME Slave images in the Universe ASIC give
other VMEbus masters access to any devices on the board. The
combination of the four Universe VME Slave images and the four Raven
PCI Slave decoders offers great flexibility in mapping the system
resources as seen from the VMEbus.
In most applications, the VMEbus needs to see only the system memory
and, perhaps, the software interrupt registers (SIR1 and SIR2 registers).
For an example of the VMEbus slave map, refer to the figure below:
