An early slice prototype for the upgraded readout electronics of TileCal

We have developed a slice prototype of the full TileCal readout chain based on prototype modules and off-the-shelf components. As different module prototypes are developed and become available they can replace earlier prototypes or emulators in the chain. Due to its modular and flexible structure, the prototype can adapt to changing requirements. This will allow most of the final functionality to be developed and tested before the hardware design is finalized.
