Abstract

In this paper we show a reconfigurable hardware architecture for the acceleration of video-based driver assistance applications in future automotive systems. The concept is based on a separation of pixel-level operations and high level application code. Pixel-level operations are accelerated by coprocessors, whereas high level application code is implemented fully programmable on standard PowerPC CPU cores to allow flexibility for new algorithms. In addition, the application code is able to dynamically reconfigure the coprocessors available on the system, allowing for a much larger set of hardware accelerated functionality than would normally fit onto a device. This process makes use of the partial dynamic reconfiguration capabilities of Xilinx Virtex FPGAs.
