GPGPU for industrial control systems

In this work in progress paper we present parts of our ongoing work on using the Graphical Processing Unit (GPU) in the context of Embedded Systems. As a first step we are investigating the possibility to move functions from a Digital Signal Processor (DSP) to a GPU. If it is possible to make such a migration then it would simplify the hardware designs for some embedded systems by removing external hardware and also remove a potential life cycle issue with obsolete components. We are currently designing a test system to be able to compare performance between a legacy control system used today in industry, based on a CPU/DSP combination, to a new design with a CPU/GPU combination. In this setting the pre-filtering of sampled data, previously done in the DSP, is moved to the GPU.
