Operating Systems for Multiple Arrays of Microprocessors Used in a Hybrid Prompt Diagnostic System

Two operating systems are described which enable arrays of interconnected DEC LSI-ll microprocessors to control and to automatically record data from digital measurement devices the Lawrence Livermore Laboratory uses in its Hybrid Prompt Diagnostic System (HPDS) to accomplish high-speed capture of analog and digital data at the Nevada Test Site. The modular design of these operating systems permits the software to support an infinite variety of digital measurement devices without changes in the basic operating systems other than programming of command control software for each new type of measurement device added to the system.
