FLASH存储器、FPGA芯片以及FPGA芯片的配置方法
摘要：
本发明公开了一种FLASH存储器、FPGA芯片和FPGA芯片的配置方法，其中，FLASH存储器用于与FPGA芯片的专用配置电路相连；FLASH存储器存储有配置文件以及MAC地址，配置文件存储在FLASH存储器的第一存储地址中；MAC地址存储在FLASH存储器的第二存储地址中；配置文件包含有第一配置数据，第一配置数据用于供专用配置电路生成与FLASH存储器相连的指示功能电路，并将指示功能电路的操作地址指向所第二存储地址，以使得指示功能电路能够获取到第二存储地址中的MAC地址；其中，MAC地址为FPGA芯片的唯一地址，在本发明中，无需为FPGA芯片增加任何外围电路来进行MAC地址的修改，从而减少了增加外围电路所需的布线成本，节约了资源。
摘要（英）：

The invention discloses a flash memorizer, an FPGA chip and a configuration method of the FPGA chip. The flash memorizer is used for being connected with a special configuration circuit of the FPGA chip. A configuration file and an MAC address are stored in the flash memorizer. The configuration file is stored in a first storage address of the flash memorizer, and the MAC address is stored in a second storage address of the flash memorizer. The configuration file comprises first configuration data for the special configuration circuit to generate an indication function circuit connected with the flash memorizer, and an operation address of the indication function circuit points to the second storage address so that the indication function circuit can obtain the MAC address in the second storage address. The MAC address is the only address of the FPGA chip. According to the flash memorizer, the FPGA chip and the configuration method, any peripheral circuit does not need to be arranged for the FPGA chip for correcting the MAC address, and therefore the wiring cost needed by arranging of the peripheral circuit is reduced, and the resource is saved.
