EDMA 3 传输不同类型数据配置



1 使用 EDMA3 传输 int[x][x] 类型的二位数组 Param 如何配置;

  尤其是aCntbCnt 这个位  对于acnt 和 bcnt的值不知如何计算;

  例如 int buf [128][1024]?

  那么 aCntbCnt  应该如何配置

2 若为 double  buf [128][1024];  aCntbCnt 又该如何配置?

myParamSetup.option = 0x0010000c;
myParamSetup.srcAddr = (Uint32)buf;
myParamSetup.aCntbCnt = 0x10000080; 
myParamSetup.dstAddr = (Uint32)dstbuf;
myParamSetup.srcDstBidx = 0x00200500;
myParamSetup.linkBcntrld = 0x0000ffff;
myParamSetup.srcDstCidx = 0x0;
myParamSetup.cCnt = 0x00000001;
