PCI Express
High transfer rates without detours
In many areas of image processing, especially for mobile devices and in the field of edge computing, embedded vision modules are an increasingly relevant component. In order to be able to offer a camera platform even for demanding applications, you will find camera modules at Balluff that are equipped with the cross-platform high-performance interface PCI Express.
The PCI Express standard was introduced in 2003 and regulates the connection of peripheral devices with the chipset of the mainboard. It is a point-to-point connection with up to 16 lanes per connection, whereby the more lanes, the greater the available bandwidth.
Thanks to guaranteed Direct Memory Access, i.e. the almost latency-free transfer of data directly into the memory, a large part of the gross bandwidth of 20 Gbit/s can be used. This makes the interface suitable for embedded vision applications with high resolutions, high frame rates and short distances between camera and evaluation unit.
The advantages
Cameras with PCIe interface offer various advantages. For example, a wide variety of processor architectures based on NVIDIA, ARM and x86 are supported by the included Impact Acquire SDK. The GenICam GenTL Producer ensures compatibility with existing developments and guarantees smooth switching between different hardware platforms. Customized connection boards can also be developed as required.
