Anais do REC07 III Jornadas sobre Sistemas Reconfiguráveis Lisboa, Portugal FPGA Architectures for Reconfigurable Computing

To accelerate the execution of an application, repetitive logic and arithmetic computation tasks may be mapped to reconfigurable hardware, since dedicated hardware can deliver much higher speeds than those of a general-purpose processor. However, this is only feasible if the run-time reconfiguration of new tasks is fast enough, so as not to delay application execution. Currently, this is opposed by architectural constraints intrinsic to current Field-Programmable Logic Array (FPGA) architectures. Despite all new features exhibited by current FPGAs, architecturally they are still largely based on general-purpose architectures that are inadequate for the demands of reconfigurabl
