c6678EMIF模块与FPGA问题连接

我使用C6678EMIF口与FPGA连接时采用EMIF模块的地址线EMIFA[9：0]与FPGA设定的地址线A[9：0]一一连接，未使用手册上的EMIF模块的地址线EMIFA[23]，因此dsp程序对EMIF模块访问时需将访问地址右移两位即为EMIFA[9：0]的输出地址，现在遇到如下问题：

（1）在运行DSP程序（见附件）通过设置了一个10kHZ的定时中断不断的触发程序运行，但是程序中对其16个地址连续的写入数值后，再连续的回读进行测试，发现总是有写和读不一致的情况发生，并对发生的次数进行累加（对应通道1~16），结果见图。

（2）程序中对FPGA特定的地址设置了常数，当使用DSP的EMIF对其进行读时，如果不加（1）所述的写后在读的过程，单独对含常数的FPGA地址进行读，上一之后读的没问题，没读的错误发生，加上一之后，问题就出现了（见图通道17~48和读AAAA和5555两通道））
