  • Method and structure for loading data into several IC devices
    Patent number: 5838167
    Abstract: An apparatus and method for decreasing the amount of time necessary to load configuration data into Field Programmable Gate Arrays (FPGAs) or other integrated circuit devices. In a preferred embodiment, serially arrayed FPGAs receive a concatenated stream of data from a common data bus. As a first FPGA reaches a loading-complete state, an enabling token is passed from the first FPGA to an enabling input on the next FPGA. The process repeats until all devices are completely loaded or fully configured.
