The software is a user-level library which maps the interface hardware in user space. It is not a standard LynxOS driver. Therefore only a single copy of the data is necessary. The library uses DMA for the data transfers. Currently interrupts are not used.

It is this library that will be used for the Read-out Buffer software in the ATLAS DAQ Prototype-1 project. The ATLAS TileCal is using it in the Read-out Drivers.

• 22 August 1997. Library is ready and is being used. Code review is being done. Improvements are made in the field of reset. Performance measurements are being made with SLIDAS and SLATE.
• 22 April 1998. Library is ready and being used. Setups are made for several test beams in July 1998 (TileCal, MDT). Performance measurements published.
• 13 November 1998. Library ported to Motorola VME platform by Juanba Romance, IFIC/Valencia
• 30 November 1998. New performance measurements made by Maris Abolins et al.
