[0148] C4 shows the case where a band of 128 bits can be secured when data of
128 bits are transferred to a 256-bit port, and C5 shows the case where a band
cannot be secured when data of 128 bits are transferred to a 256-bit port.
[0149] C6 shows the case where a band of 128 bits can be secured when data of
256 bits are transferred to a 128-bit port, and C7 shows the case where a band
cannot be secured when data of 256 bits are transferred to a 128-bit port.
[0150] C8 shows the case where a band of 128 bits can be secured when data of
128 bits are transferred to a 128-bit port, and C9 shows the case where a band
cannot be secured when data of 128 bits are transferred to a 128-bit port.
We agree with the Examiner that the combination of Yokoyama and Lach does
teach the invention as set forth in claims 16 and 17. Particularly, as noted in the
discussion of claim 1 above, Yokoyama teaches rearranging an input bandwidth by
dividing it into two output bandwidths of equal size when the width of the output port is
smaller than that of the input port. Further, according to Yokoyama’s teaching, there is
no need to rearrange an input bandwidth when it is to be transferred to an output port of
the same or larger bandwidth. The ordinary skilled artisan would have duly recognized
from Yokoyama’s teachings that a determination of whether the bandwidth of the input
port is larger or smaller than that of the output port would need to be made before
deciding on whether to format the input data or not, and before transferring such input
data to the output port. We, thus, find no deficiencies in the Yokoyama reference for the
Lach reference to cure. Consequently, we find no error in the Examiner’s stated position,
which concludes that the combination of Yokoyama and Lach teaches the steps of
determining whether the width of the input port is more than the width of the output port;
submitting the data as processed when the width of the input port is not more than the
width of the output port; obtaining the width of the output port when the width of the
input port is greater than the width of the output port; formatting the data from the input
