| 摘 要： | 为满足数字存储示波器(DSO)大流量实时数据显示的需要,本文设计了一种以A ltera FPGA和T I C 5000DSP为核心的高性能液晶屏(LCD)显示控制系统。该系统只需主机直接提供采样数据和少量控制字,便可自动生成显示所需的各种菜单,完成对采样数据的处理,产生输出波形,并驱动LCD以恒定刷屏速率进行显示。系统减轻了主机负担,实现了LCD高速数据更新,提供了灵活的接口电路,并在测试中获得了每秒80帧的波形更新速率。

| Abstract: | In order to meet the need of real-time display in digital storage oscilloscope (DSO),a high-performance display control system is introduced.According to the raw sampling data and few control words from the host,the system based on Altera FPGA and TI C5000 DSP can process sampling data,generate the relative menu and the waveform,and update them to liquid crystal display(LCD).The system liberates the host from the heavy and complex digital signal processing(DSP) operations,and achieves a high waveform rate at the same time.Also,several different interfaces are designed in the system to provide the connection with different hosts.Finally,the system is applied to the certain DSO,and the waveform rate reaches 80 Hz. |
