Abstract

We present a new data acquisition system under development for the next upgrade of the LHCb experiment at CERN. We focus in particular on the design of a new common readout board, the PCIe40, and on the viability of PCI-Express as an interconnect technology for high speed readout. We describe a new high-performance DMA controller for data acquisition, implemented on an FPGA, coupled with a custom software module for the Linux kernel. Lastly, we describe how these components can be leveraged to achieve a throughput of 100 Gbit/s per readout board.
