The Intel 82540EM Gigabit Ethernet Controller architecture is optimized to deliver both high performance and PCI bus effi ciency with the lowest power and smallest die size. Using state logic design with a pipelined DMA Unit and 128-bit wide buses for the fastest performance, the Intel 82540EM controller handles Gigabit Ethernet traffi c with low network latency and minimal internal processing overhead. The controller’s architecture includes independent transmit and receive queues to limit PCI bus traffi c, and a PCI interface that maximizes the use of bursts for effi cient bus usage. The Intel 82540EM Gigabit Ethernet Controller prefetches up to 64 packet descriptors in a single burst for effi cient PCI-bandwidth usage. A 64 KB on-chip packet buffers maintains superior performance as available PCI bandwidth changes. Advanced interrupt moderation hardware manages interrupts generated by the Intel 82540EM controller to further improve system effi ciency. In addition, using hardware acceleration, the controller also offl oads tasks from the host processor, such as TCP/UDP/ IP checksum calculations and TCP segmentation.
