Resumen
The paper covers the history of development of design technologies of reconfigurable computer systems based on FPGAs of various families. Five generations of reconfigurable computer systems with high placement density, designed on the base of various FPGA families, from Xilinx Virtex-E to modern Virtex UltraScale, are described. The last achievements in the domain of design of energetic effective reconfigurable computer systems with high real performance are presented. One of such achievements is the developed liquid cooling system for Virtex UltraScale FPGAs. It provides independent circulation of the cooling liquid in the 3U computational module with the 19?? height for cooling of 96-128 FPGA chips that in total generate 9.6-12.8 kWatt of heat. The distinctive features of the designed immersion liquid cooling system are high cooling efficiency with power reserve for the designed perspective FPGA families, resistance to leaks and their consequences, and compatibility with traditional water cooling systems based on industrial chillers.
