This paper presents a new event-driven processing platform which uses a mixture of Digital Signal Processors (DSP) and Field Programmable Gate Arrays (FPGA) to provide data reduction and real-time processing and control capabilities for long discharge fusion experiments. The architecture and physical implementation aims to provide more processing power, a mathematical algorithm description interface, and an easy integration with existing acquisition systems as well as the seamless integration with an event-driven data acquisition and control system for current and upcoming fusion experiments. A complete framework from the algorithm description to the physical implementation of the new platform in a heterogeneous processing system will be described in the next sections.
