eBus Optimal Driver
The eBus Optimal Driver is our recommended driver for applications demanding high
bandwidth. The driver is a purpose-built replacement for the regular driver that comes
with Intel PRO/1000 card or 825xx chip. Designed to maximize throughput and minimize
CPU usage, this driver is ideal for high-bandwidth applications that need virtually all the
CPU for other application tasks. (It also supports corporate network connectivity.)
Efficiency ★★★★★
Usage High bandwidth with CPU-intensive applications
Limitations Requires NIC from Intel’s family of PRO/1000 cards and 825xx chips
eBus Universal Driver
The eBus Universal Driver replaces the CPU intensive Windows network stack. It works
with almost any NIC because it works in conjunction with your NIC’s regular driver. It
supports corporate network connectivity.
Efficiency ★★★★☆
Usage High bandwidth application that can tolerate some sharing of the CPU
capacity
High Performance Driver Mode
If you are upgrading your existing systems, have an existing project, and you don’t
require a GigE Vision compliant connection, then we recommend that you continue to use
your current driver.
In high-performance mode, the Spyder3 GEV works with the High-Performance IP
Device Driver to transfer data between cameras and PCs with very low, predictable
latency at rates of up to 1 Gb/s (100 MB/s). The video data is streamed directly into PC
memory using almost no PC CPU resources. This leaves the CPU free to process
applications.
Efficiency ★★★★★
Usage Existing projects requiring high-bandwidth
Limitations Requires NIC from Intel’s family of PRO/1000 cards and 825xx chips
To achieve this performance level, PCs must be equipped with a GigE network interface
(also referred to as a network adapter) based on Intel’s 82540 chip. Many motherboard
manufacturers have designed this chip directly into their board in “LAN on the
motherboard (LOM)” implementations. Alternately, an Intel 82540-based network
adapter, also known as a network interface card, can be slotted into a PC.
The High-Performance IP device driver is very efficient but disregards regular Internet
traffic. Because of this, it doesn’t support corporate network connectivity.
