  Within this proceeding, we introduce the U-Board platform, a versatile
platform for signal generation, acquisition and processing, based on a
heterogenous processing architecture. Based on this platform we present a
readout for Microwave Kinetic Inductance Detectors (MKIDs) for the A-MKID
camera for APEX. In addition to the implementation of the readout on this
heterogenous architecture, we also present a first comparison of the
performance of the readout compared to the currently used readout of the A-MKID
camera. Last but not least, we discuss how we plan to miniaturize the current
prototype, which is based on commercial off the shelf components.
