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
.
