Abstract

The ATLAS experiment at LHC planned to upgrade the existing Pixel Detector with the insertion of an innermost silicon layer, called Insertable B-layer (IBL). A new front-end ASIC has been foreseen (named FE-I4) and it will be read out with improved off-detector electronics. In particular, the new Read-Out Driver card (ROD) is a VME-based board designed to process a four-fold data throughput. Moreover, the ROD hosts the electronics devoted to control operations whose main tasks are providing setup busses to access configuration registers on several FPGAs, receiving configuration data from external PCs, managing triggers and running calibration procedures. In parallel with a backward-compatible solution with a Digital Signal Processor (DSP), a new ROD control circuitry with a PowerPC embedded into an FPGA has been implemented. In this paper the status of the PowerPC-based control system will be outlined with major focus on firmware and software development strategies.
