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.
