3 Design and Application of the PLD-Based Reconfigurable Devices

Theoretical bases of construction and designing of the PLD–based reconfigurable devices, including the new formalized design techniques of construction and dynamic reconfiguration of architecture and structure of digital devices with a high degree of reconfiguration, corresponding with properties of performing algorithms, constructive and technological features PLD, and also tool means of their designing, are presented. Bases of the theory of adaptive logic networks, intended for the solution of a wide class of tasks by direct structural realization of algorithms of processing and direct representation of input data to output data by functional and structural customization for universal components of a network, are developed. Synthesis algorithms of adaptive logic networks on the classes of tasks set are developed. Design techniques of the computer systems with using of the standard CAD PLD (ISE Foundation) are developed. The structure of the reconfigurable computer system with the open library of configuration files for basic parametrical blocks, including the threshold device, Hemming adder, sorting devices, median filters, matrix multipliers etc. are designed.
