A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. FPGAs also make extensive use of reconfigurable, hardware-implemented, lookup tables to provide programmable hardware functionality. A scalable pipeline for designing reconfigurable organisms. The flexibility in reconfigurable devices mainly comes from their routing interconnect. Prime applications are optical protection, test systems, remotely reconfigurable add-drop multiplexers, and sensing. It was a distributed memory MIMD architecture with a reconfigurable interconnection network. These processors pass work to one another through a reconfigurable interconnect of channels. The FPGA Module may be used to implement high-performance data processing on reconfigurable fabric. Unlike the EFF machine, COPACOBANA consists of commercially available, reconfigurable integrated circuits. SRC Computers carried on development and specialized in reconfigurable computing. In reconfigurable computing and in supercomputing these terms refer to the data path width. The main processor would control the behavior of the reconfigurable hardware. To aid in designing reconfigurable systems, system configuration rules are utilized. Each domain is a full virtual machine with a reconfigurable subset of hardware resources. Another track of development is to combine reconfigurable logic with a general-purpose CPU.
