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.


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.
