The Project 8 collaboration seeks to measure the absolute neutrino mass using tritium beta decays and a new spectroscopy technique, Cyclotron Radiation Emission Spectroscopy (CRES). The initial phases of Project 8 demonstrated that CRES could be used to detect single-electron cyclotron radiation, and could be applied to measure the tritium beta-decay spectrum. The current phase of Project 8 will use a cylindrical array of up to 75 radio-frequency antennas to detect the cyclotron radiation from electrons in a $\sim$10 cm$^3$ fiducial volume. The data-acquisition and signal-processing (DAQ) system will assemble the signals from the antenna array using digital beamforming, and perform real-time triggering and reconstruction of the electron events. The digital-beamforming aspect presents a compelling challenge in designing a real-time DAQ system. We will present the DAQ architecture that is under development, and how we plan to address the DAQ requirements of the upcoming experiment.
