    "abstract": "The SPring-8 control system provides data acquisition software called\nPoller/Collector for periodic data taking. Its polling scheme does not support\ntaking data synchronized with an event, and simultaneity in the data from the\ndifferent VME systems is not guaranteed. Recently, requirement for fast and\nevent-driven data acquisition has increased, and the synchronization of a set\nof data from the different VME systems is requested. We added new data-taking\nsoftware to the standard framework with a shared memory network. We designed\nthe software on the VME by updating the original framework that was already\nused for feedback control. The data filling process on a PC stores sets of the\nsynchronized data on a shared memory board to the database. The shared memory\nboards provide 250Mbit/s transmission rate and are linked with optical fiber\ncables. We will install the system to the linac beam position monitors data\nacquisition as the first application.",
