The following figure shows how start, offsets, and step work on the cint16 data type.

Figure 1. MAC4 on cint16 x cint16 Type

mac4 has four output lanes. The first column of data is selected by adding xstart to every 4 bits of xoffsets. The subsequent column of data is selected by adding xstep to its previous column.

The coefficients of mac4 are chosen similarly by zstart, zoffset, and zstep.
