fpga 通过srio发送数据到dsp ，dsp从哪个寄存器读取收到的数呢？判断哪个寄存器是否收到数了？谢谢
初始化 srio_init();
配置好，SRIO会把数据直接发到DDR上面。
数据发送完会触发DSP中断
一、那我通过判断哪个寄存器来判断我收到了数了呢？
二、我通过外部SWITCH回环， dsp通过srio_write函数发送数据到0x900200 ,我时候能直接在L2缓存中看到数据呢？
pdata = (Uint32 *)0x900000; for (i = 1; i < 64; i++) *pdata++ = i + (i << 8) + (i << 16); paddr = 0x900200; srio_write(0x900000, paddr, 16);
