Abstract: A method and apparatus are presented for an improved data transferring technique between a network and a computing system. A network adapter implements a data transfer from a network to the memory of a destination computing system, accumulating a checksum of all data transferred. The dedicated hardware allows data to be transferred through it and a checksum to be accumulated without intervention by the processor of the destination computing system. Software corrections can generate a checksum of the header data and then generate a net checksum by subtracting the header checksum from the gross checksum accumulated by the dedicated hardware, thus achieving the desired result with minimal intervention by the processor of the destination computing system.

Abstract: In method for electrically connecting sections of a split plane in a printed circuit board, conductive strips are placed on a surface plane of the printed circuit board, along borders of the sections of the split plane. The conductive strips are connected to the sections of the split plane through vias. For every first section and second section which are to be electrically connected, a single piece of conductive material is connected to a conductive strip placed on a border of the first section and is connected to a conductive strip placed on a border of the second section. Testing may then be performed to determine electromagnetic properties of the printed circuit board for different combinations of the sections being connected together. From the results of the testing the optimal borders for the split plane can be determined.
