摘要： A system for multicasting a packet of data to a single data stream is provided. The system may determine a size of the packet and may send a single copy of the packet if the size of the packet exceeds a threshold value. A number of copies of the packet yet to be multicast may be ascertained if the size of the packet of data does not exceed the threshold value. Copies of the packet may be transmitted based on the number of copies of the packet yet to be multicast.

摘要： Output logic generates read requests using a programmable schedule that controls read bandwidth for multiple data streams and stores the read requests in a queuing device. The output logic also dequeues the read requests based on a similar programmable schedule, forwards the read requests to the memory, and reads data units from the memory based on the read requests.

摘要： A packet header processing engine includes a level 2 (L2) header generation unit and a level 3 (L3) header generation unit. The L2 and L3 header generation units are implemented in parallel with one another. The L2 generation unit writes L2 header information to a first buffer and the L3 generation unit writes L3 header information to a second buffer. When the L2 and L3 header generation units finish processing a packet, the packet may be unloaded from the first and second buffer while a new packet is simultaneously loaded to the packet header processing engine.

摘要： A packet header processing engine includes a level 2 (L2) header generation unit and a level 3 (L3) header generation unit. The L2 and L3 header generation units are implemented in parallel with one another. The L2 generation unit writes L2 header information to a first buffer and the L3 generation unit writes L3 header information to a second buffer. When both the L2 and L3 generation units complete their operations for a particular packet, a build component combines the generated L2 and L3 header information from the buffers to form a complete packet header.

摘要： A system for determining a memory read latency includes a memory, a memory read circuit, and a latency detector. An identifiable pattern of data is written to at least one location in the memory, and a read request and the address of the identified pattern are sent to the memory. The latency detector determines a read latency period based on detecting the identifiable pattern of data.

摘要： A packet header processing engine receives a header of a packet. The received header includes a size of the packet. A maximum transfer unit size of a destination interface of the packet may be determined. The packet header processing engine determines whether the size of the packet exceeds the maximum transfer unit size of the destination interface. If the size of the packet does not exceed the maximum transfer unit size of the destination interface, the packet header processing engine generates a new header from the received header. If the size of the packet exceeds the maximum transfer unit size of the destination interface, the packet header processing engine generates a fragment header from the received header. The packet header processing engine may recycle the fragment header for further processing in addition to forming a first fragment packet from the fragment header.
