Abstract: EXCALIBUR is an advanced photon counting detector being designed and built by a collaboration of Diamond and the STFC. It is based around 48 CERN Medipix3 chips arranged as an 8 x 6 array. The main problem addressed by the design of the hardware and software is the uninterrupted collection and safe storage of image data at rates up to one hundred 2048 x 1536 frames per second. This is achieved by splitting the image into 6 ‘stripes’ and providing a parallel data path for each stripe all the way from the detector chips to the storage. This architecture requires the software to control the configuration of the stripes in a consistent manner and to keep track of the data so that the stripes can be subsequently stitched together into frames.
