随着遥测遥感采集技术的迅速发展,大批量采集数据的有效传输已经成为当前无线遥测领域研究的热点问题,本设计基于NiosⅡ软核技术,能够同时完成两路最高速度不大于240Mbps的LVDS图像数据的解码、接收,并将数据缓存到由两片16位PSRAM并联形成的缓存模块中,并且通过一路PCM信号进行转发,码率大小为1.26MHz,测试结果表明系统工作稳定,性能可靠,具有一定的实用性。
With the rapid development of telemetry and remote sensing acquisition technology, the effective transmission of high-volume data acquisition has become a hot issue in the field of wireless telemetry. This design is based on Nios Ⅱ soft-core technology and can simultaneously process two LVDS image data with a maximum speed of not more than 240 Mbps The data is buffered in a buffer module formed by parallel connection of two 16-bit PSRAMs and is forwarded through one PCM signal at a bit rate of 1.26MHz. The test results show that the system is stable in operation, reliable in performance and has certain performance Practicality.
