Abstract
For the ATLAS experiment at the Large Hadron Collider (LHC) buffers ar e required which will accept data at rates in excess of 100 Mbytes/s a nd distribute selected data to the second and third level trigger syst ems. A design for a buffer using a digital signal processor as the mem ory manager is described and the performance of a prototype module is given. Tests of the system in a beam line will be used to develop and check discrete event simulation models of the buffers and a second lev el trigger system.
