Abstract :
The FPGA market has evolved at an extremely rapid pace, with larger and faster devices being released to the industry by different vendors. One has to select a target FPGA device that suits one´s application. This paper presents a survey of currently available dynamically reconfigurable FPGA devices. The devices were: the Atmel AT40k family, the Xilinx Virtex family, the Lattice Semiconductors ORCA and ispXPGA families, and the Altera APEX20k family. The degree of dynamic reconfigurability of these devices was compared based on partial or full reconfiguration. The architectures of these devices were evaluated based on the granularity and reconfiguration time.
