| 摘 要： | 纠错技术是现代通信系统不可缺少的技术,针对目前纠错码测试可重构性要求高和测试数据量大的特点,提出了一种针对纠错码的基于分层原理的软硬件联合测试平台。采用分层的设计结构,使得该平台具备高度的可重构性,能够在不同纠错码测试之间进行迅速重构。利用高速的PCI数据采集卡PCI-7300A在PC和FPGA之间进行数据传输,并在PC和FPGA端对数据进行分层封装和添加校验与确认—重传机制,以此保证数据高速、顺序、无差错地传输。通过利用该平台对多进制LDPC码进行测试,结果表明,在传输时钟为20MHz的时候,平台吞吐量达到446.83Mbit/s。

| Abstract: | The error correcting technology is indispensable in modern communication system.In this paper,in order to meet the high reconfigurable requirement of current error correcting test,a new error correcting codes(ECC)test platform was proposed based on the layer principle and the hardware-software co-design.The layering design construction enables the platform of high reconfiguration ability,which reconfigures quickly between the different ECC.In order to ensure the high-speed,ordinal and error-free data transm... |
