Abstract

The invention discloses an anti-loss temporary data transfer device, which comprises a signal receiver, a signal conditioning module A, a signal conditioning module B, a data buffer, a DSP processor, an analog-to-digital converter A, an analog-to-digital converter B, a dual RAM, interface chip, program memory, synchronous burst static memory and uninterruptible power supply; the present invention applies the PCI interface to the DSP system, accelerates the speed of data transmission, can make full use of the hardware resources of the PC, and completes data fusion , target display, parameter setting and other tasks. The tasks with large amount of computation and strong real-time performance are handed over to the DSP chip to complete, making full use of the special features of the DSP chip, thus realizing the complementary advantages of the PC and the DSP system. The organic combination of the two can build a signal processing system with strong real-time performance, friendly interface, and convenient operation. At the same time, the device also uses a non-simple power supply to prevent data loss caused by power failure during data transfer.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to an anti-loss temporary data transfer device. Background technique [0002] With the improvement of the performance of the digital signal processor (DSP) and its peripheral support chips, software radio has been widely used, which greatly enhances the overall performance of the real-time signal processing system. But on the other hand, as the ADC and DAC move forward to the radio frequency direction, the sampling frequency of the signal also increases accordingly, which makes the bandwidth of the data exchange of the DSP system increase exponentially. The bottleneck effect of the traditional data exchange interface is becoming more and more obvious, so a batch of new interface standards have been born accordingly. Since the PCI interface was proposed in 1993, it has been supported by many computer equipment manufacturers and has been widely used in related fields such a...
