The structure and basic processes of data acquisition software of the DIRAC
experiment for the measurement of pi (+)pi (-) atom lifetime are described
. The experiment is running on the PS accelerator of CERN. The developed so
ftware allows one to accept, record and distribute up to 3 Mbytes of data t
o consumers in one accelerator supercycle of 14.4 s duration. The described
system is successfully in use in the experiment since its startup in 1998.
