Within the DSP applications, which are computationally intensive and desirable for parallel processing,programmable processors and ASICs have their own advantages and defects respectively. Consequently a new computing paradigm-reconfigurable computing has received wide attention and under extensive researches due to its ability to combine the efficiency with flexibility. The paper introduces the basic concept and taxonomy of reconfigurable computing, describes some main-stream reconfigurable systems and analyzes their characteristics. Then the paper discusses the challengesand directions in developing computation models, compiler, mapping technique, as well as entire development environment for the reconfigurable architectures, and draws the conclusions.
