Abstract
Abstract
Today, most X-ray pixel detectors used at light sources
transmit raw pixel data off the detector ASIC. With the availability
of more advanced ASIC technology nodes for scientific application,
more digital functionalities from the computing domains (e.g.,
compression) can be integrated directly into a detector ASIC to
increase data velocity. In this paper, we describe a lightweight,
user-configurable detector ASIC digital architecture with on-chip
compression which can be implemented in 130 nm technologies in a
reasonable area on the ASIC periphery. In addition, we present a
design to efficiently handle the variable data from the stream of
parallel compressors. The architecture includes user-selectable
lossy and lossless compression blocks. The impact of lossy
compression algorithms is evaluated on simulated and experimental
X-ray ptychography datasets. This architecture is a practical
approach to increase pixel detector frame rates towards the
continuous 1 MHz regime for not only coherent imaging techniques
such as ptychography, but also for other diffraction techniques at
X-ray light sources.
