scan 2 columns from DDR/HBM buffers.
The LSB of first vector of first column specifies the number of rows to be scanned. For a following buffer, if the first vector is zero, same number of zeros will be emitted, otherwise, same number of rows will be read from the buffer.
Parameters:
| burst_len | burst read length, must be supported by MC. |
| vec_len | scan this number of items as a vector from AXI port. |
| ch_nm | number of concurrent output channels per column. |
| size0 | size of column 0, in byte. |
| size1 | size of column 1, in byte. |
| c0vec_ptr | buffer pointer to column 0. |
| c1vec_ptr | buffer pointer to column 1. |
| c0_strm | array of column 0 stream. |
| c1_strm | array of column 1 stream. |
| e_row_strm | array of output end flag stream. |
