Since the PCI-E 1.0a specification in 2004, the latest serial high-speed PCI-E bus has been on the motherboard. Compared with the original PCI V2.3, the PCI-E bus has great advantages. First, PCI- E reduces the number of pins connected to the chip, simplifies the design and layout of the PCB; secondly, PCI-E is a non-shared serial differential interface, there is no case where multiple devices share bandwidth, the theoretical bandwidth of PCI-E x1 For transmission and reception of 250 Mbytes/second, the theoretical bandwidth of PCI-E x4 is 1 Gbyte/sec for transmission and reception, and a higher-speed physical layer transceiver of 5G BPS is used in the PCI-E 2.0 protocol. The speed will double. Therefore, the PCI-E bus interface is particularly suitable for ultra-high-speed data transfer, and will replace the PCI interface within 3 years. In accordance with this situation, our company has launched the S2300 PCI-E interface FPGA development experimental platform to meet the needs of the market, to meet the needs of users for high-speed data transmission.
The development experiment board adopts PCI-E x1 interface, which provides 80 available FPGA IO inputs and outputs for user-friendly development. Users can design application interface boards, such as external A/D data acquisition and image data processing. System applications, without having to know too much about the PCI-E interface.
PCI-E interface chip adopts PLX8111BB66BC of PLX company, fully supports PCI-E 1.0A protocol, external interface supports up to 66M working frequency, 32-bit bus width, supports burst peak transmission speed of up to 266M bytes/second.
The core FPGA chip adopts ALTERA's new CYCLONE FPGA series, EP1C12Q240C8, with a capacity of 12,000 logic macrocells respectively, equivalent to the standard 300,000 logic gates, with a speed of -8. The compiled system speed can reach 100MHz, which can support ALTERA. The development of the SOPC kernel NIOS2 system, the compiled executable file of the NIOS2 development environment can be downloaded to the FLASH on the development board through the PCI interface.

Generators refer to mechanical equipment that converts mechanical energy into electrical energy, which is driven by hydraulic turbines, steam turbines, diesel engines or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy, which is then transferred to the generator, and then converted to electrical energy by the generator.
Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. Generators have many forms, but their working principles are based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is to use appropriate magnetic and conductive materials to form the magnetic circuit and circuit for mutual electromagnetic induction, so as to generate electromagnetic power and achieve the purpose of energy conversion.
Diesel generator is a small power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as prime mover to drive the generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control box, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components.It can be used for daily power generation and emergency power generation of various families, offices, large, medium and small enterprises.
