Abstract

The mechanism of including new module and functionality to modern USB bus is proposed. This allow to put USB device into hibernation and make decrease of consumed power up to 90 percent if device is in suspended state and not activate on USB. Offered module is completely powered-off while core functions in normal mode. Logic is implemented on Verilog Hardware description language and tested on FPGA of Virtex family. Necessary changes in USB device driver to support hibernation has been done. Because of included logic core’s occupied area increased by dimensions needed to place 2000-2500 gates which makes up only 3.5 percent of element’s total number
