Paper Abstract

The ability of rapidly reconfigure the gate-level logic of SRAM-based FPGAs at run-time allows algorithm implementations to be both adaptive and highly application- specific. In this way, adaptive algorithms can be implemented in hardware, and deliver high performance with a flexibility not normally associated with an application- specific solution. This paper describes the static implementation and operation of an adaptive image- enhancement algorithm called SUSAN on a Xilinx XC4085XL, demonstrating order-of-magnitude performance improvements over optimized software running on high-end general-purpose processors, and discusses the implementation of adaptive solutions in both hardware and software. The effective use of dynamic reconfiguration for run-time reconfigurable systems based on XC4000-series devices is examined, along with the use of the JBits API for implementing FPGA-based adaptive signal processing algorithms. Both the performance and suitability of XC4000-series devices for adaptive processing are shown to be critically dependent on device capacity.
