Abstract


Signal and information processing information science in recent years one of the most rapidly developing discipline, with the advent of the era of system-on-chip (SOC, System On Chip), the FPGA is at the leading edge of revolutionary digital signal processing. Based on FPGA design in the system re-programming and debugging of the system, with high throughput, better able to prevent unauthorized copying, components and development to further reduce costs, and also greatly shorten the development time. However, FPGA devices are SRAM-based structure of the programming process, programming information immediately after power is lost, every power, configuration data must be re-download, and the device supports multiple configurations, so the configuration of the FPGA device program in the FPGA The system design has an extremely important value, it also gives higher requirements for the configuration of the programmable logic device programming interface circuit and experimental development equipment. This thesis is based on the IEEE1149.1 standard USB 2.0 technology, completed the design and realization of the FPGA configuration interface circuit and experimental development board. Author on the basis of full understanding of the IEEE1149.1 standards and principles of USB technology, USB data configuration for Altera Corporation dedicated cable USB-Blaster, testing with a detailed analysis of its inner workings and work timing, completion of a USB-based configuration interface FPGA chip developed a complete hardware and software design and function of the experimental circuit timing simulation. Of the final hardware and software debugging, completed testing and validation series PLD configuration capabilities of Altera and experimental development board. This article discusses the USB download interface circuit validation can directly use the in Altera's QuartusII development environment, communication software to be designed without the host side, its compatibility is improved compared to the existing design. PLD (Programmable Logic Device) manufacturers of its intellectual property is strictly confidential, so considerably limited, based on the configuration of the USB interface circuit applications but also increase the difficulty of their own design development. Download PC parallel port interface circuit, the design based on the USB download interface circuit in FPGA development board has a higher programming download speeds, hot-swappable, small size, easy to carry, reducing damage to PC hardware and with other download interface circuit SignalTapII embedded logic analyzer and the debugging NiosII embedded soft-core processors do not have obvious advantages. From a cost point of view, the design configuration of the USB interface circuit and FPGA experimental development board their strong competitive compared to similar products.
