| FPGA technology has gotten rapid development in recent years and gotten abroad used in all kinds of industries, especially in military affairs. Making use of FPGA and DSP can achieve kinds of complex arithmetic, and then make demodulation, filter wave and decode of short wave together with satellite real-time signal into reality. In addition, its merits that are small cubage and few electricity-consuming adapt itself in bad circumstance, highly flexibility department.Long distance transmission of terminal data has been the bottleneck of the whole system at all times. We adopted a sort of method which composing FPGA and DSP chip into PCI board card . This means can transfer data from board card to computer, then realize long-distance transmission by the computer. Although the transmission has been completed, what computer only acts as the medium not only wastes resource but also makes the system clumsiness(the former equipment is included in this system) and inconvenience.Therefore, whether can we let go the independent to computer and... |
