Dynamic and partial FPGA exploitation

Today's field programmable gate array (FPGA) architectures, like Xilinx's Virtex-II series, enable partial and dynamic run-time self-reconfiguration. This feature allows the substitution of parts of a hardware design implemented on this reconfigurable hardware, and therefore, a system can be adapted to the actual demands of applications running on the chip. Exploiting this possibility enables the development of adaptive hardware for a huge variety of applications. A novel method for communication interfaces using look up table (LUT)-based communication primitives enables an exact separation of reconfigurable parts and a fast and intelligent bus-system. A new adaptive software/ hardware reconfigurable system is presented in this paper, using a real application in the automotive domain implemented on a Xilinx Virtex-II 3000 FPGA to present results.
