The microprocessor subsystems provide the interface between the machine hardware and the host level computers at the NSLS facility. The micros are VME-based 68k series computers and are driven by a real-time, multi-tasking software referred to as the Micro Control Monitor. The monitor performs hardware control and data acquisition in real-time. It presents a standard equipment interface to the control and data acquisition commands from the host level application programs. The monitor also provides an easy environment for developing hardware dependent micro tasks. There are approximately seventy micros in the control system. This document describes the hardware configuration and the control monitor software. A list of the micros with a brief description of their functions is also provided.
