The DaqMux system is shown in Figure 1. The DaqMux component of the FPGA in the application board of the ATCA allows the user to choose to stream up to four streams to the software (IOC) of the input streams routed to the DaqMux. All ATCA projects are configured to have two DaqMuxes, one associated with each AMC daughter board, summing a total of 8 streams routed to software. Each of the two DaqMux has 20 streams of data routed to its input. One may assume that the DaqMux only performs multiplexing of continuous streams as denoted by the component's name, but that is not only the case. The DaqMux not only allows continuous (continuous mode) streaming of multiplexed streams, but also it allows that a fixed size of the multiplexed input streams is burst upon a reception of a trigger (trigger mode) from the timing core on the FPGA firmware.
