An embodiment of the invention provides a data transmission device. The data transmission device includes a first bus master control circuit, a second bus master control circuit, a storage circuit, a first control circuit and a second control circuit. The first bus master control circuit processes data transmissions associated with a peripheral device. The second bus master control circuit processes data transmissions associated with a system memory. The storage circuit stores information and instructions for data transmission. The first control circuit controls the first bus master control circuit according to the information and the instructions. The second control circuit controls the second bus master control circuit according to the information and the instructions.

Data transmission device with FIFO circuits for reading and writing operations and method

The speed of the network address translation translated with software is generally slower than the speed of transmitting packet in the network, so that the data stored in memory is affected. In this invention, the network address translation is translated by hardware, and a plurality of comparing engines is employed to accelerate the translating speed. Therefore, even in the worst case scenario, the time needed for translating the network address is shorter than the time needed for storing the packet into memory, so that the operation of the network address translation is assured not to affect the data transmission in the network.
