Title: FPGA architectures for reconfigurable computing
Issue Date: 2007-02
Abstract: To accelerate the execution of an application,repetitive logic and arithmetic computation tasksmay be mapped to reconfigurable hardware, sincededicated hardware can deliver much higher speedsthan those of a general-purpose processor.However, this is only feasible if the run-timereconfiguration of new tasks is fast enough, so asnot to delay application execution. Currently, this isopposed by architectural constraints intrinsic tocurrent Field-Programmable Logic Array (FPGA)architectures. Despite all new features exhibited bycurrent FPGAs, architecturally they are still largelybased on general-purpose architectures that areinadequate for the demands of reconfigurablecomputing. Large configuration file sizes and poorhardware and software support for partial anddynamic reconfiguration limits the acceleration thatreconfigurable computing may bring to applications.The objective of this work is the identification ofthe architectural limitations exhibited by currentFPGAs that prevent reconfigurable computingsystems to achieve a high efficiency andperformance and the proposal of alternatives to itsresolution.
