DELAY COMPENSATION FOR LARGE WINDOWS
A large window is composed of several partial windows
each of which is implemented in an individual device. If
necessary the partial window must be padded with zero
coefficients to become one of the standard sizes. When
constructing a large window it is necessary to delay the
expansion data inputs in order to compensate for growth in the
horizontal direction. Delays in the partial sums are also
necessary to compensate for the total pipeline delay needed
to produce the previous complete horizontal stripe.
Within each device in a horizontal stripe, apart from
the first, the expansion input must be delayed by the width of
the partial window, before it is added to the internal sum. Since
partial windows can only be 4 or 8 pixels wide,a delay of 4 or
8 pixel clocks is needed. There is, however, an in-built delay

of 4 pixels in the inter device connection, and the
PDSP16488A thus only needs an option to delay the
expansion input by an additional four pixels.
The data from the last device in a horizontal row of
convolvers feeds the expansion input of the first device in the
next row. This is shown in Figure 6. With this arrangement, the
position of the partial window as illustrated, is the inverse of
its vertical position on a normal TV screen. Thus the top, left
hand, device corresponds to the bottom, left hand, portion of
the complete window.
The output from the last device in the row is delayed
with respect to the original data input by an amount given by
the formula;
DELAY = 4 + [N-1].S where N is the number of devices in
a row and S is the partial window width, ie 4 or 8.
