sPHENIX
sPHENIX is a state-of-the-art jet and heavy flavor detector planned at the Relativistic Heavy Ion Collider (RHIC). Its data acquisition is a hybrid of multiple types of streaming-readout front-end electronics (FEE) from the tracking system, and a triggered event readout from the calorimeters. The experiment will have a disk throughput of 100-200 Gbps. A detector concept for an electron ion collider (EIC) is also developed based on the sPHENIX detector and the sPHENIX DAQ architecture, then in a full streaming mode. At the core of the streaming readout, large FPGA-based interface cards ("FELIX" BNL-712 cards) are used to distribute timing to and zero-suppress, compress, package data from custom front-end boards. The PCIe-based FELIX cards interface the front-end with standard Linux computers. The concept of this DAQ system and recent development highlights will be discussed in this talk.
