摘要： The present invention relates to a programmable-gate-array copy protection method and a system which prevent unauthorized copying of an FPGA program. A copy protection method for a field-programmable gate array, the method comprising a step of causing a user-specific gate array to boot a user circuit data to the field-programmable gate array, the user-specific gate array being connected to the field-programmable gate array and a memory device in which the user circuit data is stored and being pre-programmed at a semiconductor-vender's factory.

摘要： The configuration of a system including a lot of receiving side devices can be simplified. The system includes a driver 10 and receivers 21 to 2N. The driver 10 and each of the receivers 21 to 2N are configured to be daisy chain connected, thereby performing data communication. The data communication is herein performed by serial communication. The driver 10 includes a PS/SP conversion 12, and transmits serial data obtained by conversion by the PS/SP conversion unit 12. Each of the receivers 21 to 2N includes a PS/SP conversion unit 33, and converts the received serial data to parallel data by the PS/SP conversion unit 33.

摘要： A copy protection circuit to prevent illegal copy of a circuit configuration data when the user circuit data is read out and transferred from a storage device to a rewritable gate array (FPGA), includes a control circuit, a data generating circuit and a data switch circuit. The control circuit controls transfer of the circuit configuration data from the storage device to the FPGA, and the data generating circuit generates pseudo circuit configuration data. The data switch circuit transfers to the FPGA, the circuit configuration data read out from the storage circuit and the pseudo circuit configuration data outputted from the data generating circuit. The data switch circuit transfers to the FPGA the circuit configuration data which is less than a data amount that the FPGA needs, and then the pseudo circuit configuration data.
