Proposal for USB2.0/1.1 function modeling system - an application of FPGA to the USB emulation system

摘要

Despite the increasing complexity of USB function system, market does not allow engineers to spend enough time for development. To satisfy market's requirement (i.e. engineers' requirement), brand-new system called "EmuAid-USB" has been released. Applying our original IP cores combined with our knowledge of FPGA prototyping and driver coding, "EmuAid-USB" became as an useful software/hardware development tool for USB function system. With this article, USB2.0/1.1 function modeler "EmuAid-USB"'s actual development example and its application are introduced, not only for the firmware and device-driver engineers, but also for the hardware engineers as well.
