Operating Principles of the SBus MultiKron Interface Board | NIST

The MultiKron 1 Experimenter's Toolkit contains a MultiKron interface printed circuit board (currently we have interface boards for the VME bus, SBus, and PCI bus), installation software, data logging software, and analysis software; all of the software supplied is written in C. The Toolkit allows users to take advantage of the NIST MultiKron performance measurement chips (Mul-tiKron II and MultiKron vc) in systems that do not already have a MultiKron designed into them. The toolkit board is applicable to both multiprocessor systems and single-processor systems. The Experimenter's Toolkit allows researchers to obtain hands-on experience with the MultiKron performance measurement chips, without the engineering eeort required to design and build a hardware interface between the MultiKron and their computer. Over 800,000 Trace Samples can be collected via the MultiKron II during an experiment to the dedicated toolkit board memory; a practically-unlimited number of Samples can be collected if an optional external data-collection computer is used. The optional MultiKron vc chip provides 8,192 virtual counters.
