Abstract

A network interface controller including a data alignment module, a boundary determination module and a checksum module is provided. The data alignment module receives raw data and re-combines the raw data as first valid data, wherein the raw data includes a first layer protocol segment and a second layer protocol segment. The boundary determination module receives the raw data in parallel to the data alignment module and performs a boundary determination operation on the raw data to generate a boundary information indicating a boundary between the first layer protocol segment and the second layer protocol segment. The checksum module is coupled to the data alignment module and configured to disassemble the first valid data as second valid data and calculate a checksum according to the boundary information and the second valid data.

Dependent claims

A network interface controller, comprising:

a data alignment circuit, receiving at least one raw data comprising valid data and invalid data, and re-combining all of the valid data in the raw data as a first valid data, wherein the raw data comprises a first layer protocol segment and a second layer protocol segment;
a boundary determination circuit, receiving the raw data in parallel to the data alignment circuit and performing a boundary determination operation according to the raw data to generate a boundary information, wherein the boundary information is used to determine a boundary between the first layer protocol segment and the second layer protocol segment;
and
a checksum circuit, coupled to the data alignment circuit and configured to:
disassemble the first valid data as at least two second valid data, wherein a length of each of the second valid data is smaller than a length of the first valid data;
and
calculate a checksum of a second layer protocol according to the boundary information and the second valid data.
