摘要： A network processor system includes a network processor 1, which is provided with a number of interfaces 9, 11, 13, 15, 19, including one or more Ethernet interfaces 9, 11 and a UART interface 19, which can be used to load a software package into the network processor 1. The software package can thus be modified when required, or when the software package previously stored in the network processor system is corrupted. The Ethernet data packets received on the Ethernet interfaces 9, 11 are in a special format, which the network processor 1 can recognize, to distinguish them from conventional Ethernet packets. Thus, the network processor 1 does not have to be programmed to handle the full range conventional Ethernet data packets. The network processor 1 is provided with a second external non-volatile data storage device 7 in the form of a EEPROM memory 7. The EEPROM memory 7 provides a writable extension of the internal ROM memory of the network processor. It can, for example, be used to store the parameters of other components of a network processor system (e.g. a flash memory 5) so that the network processor 1 can be used in conjunction with components of a wide range of types.

EEPROM存储器7提供网络处理器的内部ROM存储器的可写扩展。例如，其可以用于存储网络处理器系统（例如，闪存5）的其他组件的参数，使得网络处理器1可以与广泛类型的组件结合使用。

摘要： There is provided an apparatus and method for transferring data packets from a peripheral module to a memory via a memory-controller. When a given peripheral module requests that it send a data packet to the memory via the memory-controller, the memory-controller sends an acknowledgement indicating that the peripheral module can send the data packet, whether or not there is a descriptor for the data packet. If there is a descriptor, the memory-controller receives the data packet from the peripheral module and stores it in the memory. If there is not a descriptor, the memory-controller discards the data packet as it receives it. Thus, whether or not there is a descriptor available for the data packet, the peripheral module still sends the data packet to the memory-controller. The data packets may be assigned classifications and each classification may be assigned a dedicated space in the memory.
