I want to use one of C_Callable functions of ti for C6713 DSPs. this
function gets two arrays(address of arrays is x,y). in the descriptions of this function I saw these sentences: " The arrays x and y should be aligned on opposite (even and odd) double word boundaries to avoid memory bank hits". what is the meaning of "double word boundaries" ? how can I align a variable in the memory in "even double word boundary" and "odd double word boundary". ? Regards. |

In the C compiler help, lookup #pragma DATA_ALIGN() - Andrew E.
