1. Introduction
1. Introduction
The EUDAQ software is a data acquisition framework, written in C++, and designed to
be modular and portable, running on Linux, Mac OS X, and Windows. It was written
primarily to run the EUDET Pixel Telescope[1], but is designed to also be generally
useful for other systems.
The hardware-specific parts are kept separate from the rest, so that the common parts
can still be used independently. These include software for accessing the trigger logic
unit (TLU) and the the EUDET data reduction board (EUDRB) used by the EUDET
beam telescope.
The data files generated by the DAQ can be easily converted to the Linear Collider
I/O (LCIO) format, allowing the data to be analysed with the EUTelescope[2] analysis
package.
1.1. Architecture
It is split into a number of different processes (see Figure 1), each communicating using
TCP sockets. A central Run Control provides an interface for controlling the whole DAQ
system; other processes connect to the Run Control to receive commands and to report
their status.
