Introduction
For many years the applications of FPGA devices are not limited only to prototyping or to small volume production. Since the dynamic reconfiguration techniques of FPGAs are commercially available, there are different concepts of using them for acceleration of many types of computations. Initially, the FPGAs were used as coprocessors supporting conventional, sequential processors in the most demanding calculations, where the parallel data processing inside the FPGA was very helpful. Since advanced FPGAs are equipped with processor cores, the sequential processing and parallel coprocessing can be implemented in a single die, significantly alleviating the interconnection problems between these two modules. In this paper a completely novel solution is proposed. It exploits the parallelism of data processing and resources reuse of dynamically reconfigurable FPGAs, without any impact on development of new applications as well as migration (porting) of the existing ones. The proposed solution is an FPGA-based implementation of general-purpose processor, in which there are no sequentially executed instructions but all tasks are implemented in the reconfigurable hardware, in the completely automatic way. The whole array of configurable blocks can be modified at runtime, except for small part responsible for reconfiguration management.
