The document discusses concepts related to partial dynamic reconfiguration. It defines key terms like reconfigurable computing, object code, reconfiguration controller, and reconfiguration manager. It also discusses the 5 Ws of reconfiguration - who controls it, where the controller is located, when configurations are generated, which is the granularity, and in what dimension it operates. Examples of reconfiguration in everyday life like sports are provided. Reconfigurable architectures are characterized based on factors like embedded vs external, complete vs partial, and dynamic vs static. Finally, more definitions related to cores, IP cores, and reconfigurable functional units and regions are given.

6. Reconfigurable Computing “ Reconfigurable computing is intended to fill the gap between hardware and software, achieving potentially much higher performance than software, while maintaining a higher level of flexibility than hardware” (K. Compton and S. Hauck, Reconfigurable Computing: a Survey of Systems and Software , 2002)

7. Some Definitions Object Code : the executable active physical (either HW or SW) implementation of a given functionality Reconfigurable Computing : the ability of altering a concrete architecture (microarchitecture), once it has been deployed, to meet at the best the execution mode of object code Reconfiguration Controller : the element that is responsible for the physical implementation of a reconfiguration process i.e., in Xilinx FPGA the ICAP controller Reconfiguration Manager : the element that is responsible for the management of a reconfiguration process i.e., in ATMEL the AVR microcontroller, in Xilinx the PPC405 Relocation : the ability of moving an object code from a location to a new one

12. More Definitions Core : a specific representation of a functionality. It is possible, for example, to have a core described in VHDL, in C or in an intermediate representation (e.g. a DFG) IP-Core : a core described using a HD Language combined with its communication infrastructure (i.e. the bus interface) Reconfigurable Functional Unit : an IP-Core that can be plugged and/or unplugged at runtime in an already working architecture Reconfigurable Region : a portion of the device area used to implement a reconfigurable core
