Abstract :
The research project RD24 is studying applications of the scalable coherent interface (IEEE-1596) standard for the Large Hadron Collider (LHC). First SCI node chips from Dolphin were used to demonstrate the use and functioning of SCI´s packet protocols and to measure data rates. We present results from a first, two-node SCI ringlet at CERN, based on a R3000 RISC processor node and DMA node on a MC68040 processor bus. A diagnostic link analyzer monitors the SCI packet protocols up to full link bandwidth. In its second phase, RD24 will build a first implementation of a multi-ringlet SCI data merger
