The efficient vertical stabilization (VS) of plasmas in tokamaks requires a fast reaction of the VS controller, for example, after detection of edge localized modes (ELM). For controlling the effects of very large ELMs a new digital control hardware, based on the Advanced Telecommunications Computing Architecture™ (ATCA), is being developed aiming to reduce the VS digital control loop cycle down to an optimal value of 10 (s) and improve the algorithm performance. The system has 1 ATCA™ processor module and up to 12 ATCA™ control modules, each one with 32 analog input channels 12 bit resolution, 4 analog output channels 12 bit resolution, and 8 digital input/output channels. The Aurora™ and PCI Express™ communication protocols will be used for data transport, between modules, with expected latencies below 2 s. Control algorithms are implemented on a ix86 based processor with 6 Gflops and on field programmable gate arrays with 80 GMACS, interconnected by serial gigabit links in a full mesh topology.
