Abstract :
This paper presents a method to achieve backplane data transfer capabilities to and from a VME Rear Transition Module (RTM), while being in full compliance with the VME64/VIPA Specification. The VME bus is specified for data transfers only with boards plugged on the front side of the subrack. The RTMs receive power from the crate, but are not part of the actual data transfer bus. They do not plug into the J1 connector, and have no access to backplane interface logic. In this implementation, the RTM uses the feed-through pins located in the J2 connector to communicate with the corresponding front module. The front module´s internal data, address, and control buses are extended to the rear. This allows the front module´s interface block to control data transfers for logic devices on both sides of the same slot. All usual VME protocols to logic devices on the RTM become possible without any software adaptation. This method was implemented on several prototype modules developed for the ATLAS FTK Project. The full design and final test results are presented.
