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:
