About PCI Bus
Your DFE-530TX+ Adapter delivers outstanding performance by fully exploiting the advance features of your computer’s
PCI bus. DFE-530TX+ Adapters utilize the Bus Master Mode of the PCI bus, allowing direct transfers of Ethernet packet
content between computer memory and the adapter’s controller, thus minimizing network demands on the CPU. The
adapter’s controller function provides the additional benefit of reduced command processing overhead.
The working relationship between a DFE-530TX+ adapter and main memory working in Bus Master mode is powered
by the Bridge/Memory Controller of the PCI bus. This reduces the CPU role in network operations, thus freeing the
CPU to service other tasks, with resulting improvement in overall computing (multitasking) performance. At the same
time, it produces superior network throughput by reducing latency (waiting for CPU service) during transmissions and
receptions.
