Non-transparent bridging is not required in this case. Each root complex is allowed to enumerate its own endpoints. For multi-root configuration, the GX1 can be partitioned into four fixed virtual bridges supporting up to four root complexes. The GX1 supports both multi-root and multi-host configuration. Setup and diagnostics tools are available from the chip manufacturer. No programming is required to set up the ports. This way, the switch can be adapted to different backplane designs. The switch ports can be configured flexibly using an application running on the root complex CPU. This way, it is possible to build powerful and cost-effective multi-processor systems. The switch allows connection of multiple endpoints and multiple CPUs. Configurable data transfer rates can reach up to 985 MB/s per PCIe lane.įlexible Configuration of Multi-Processor Systems The GX1 enables high speed serial point-to-point communication between the CPUs and between the CPUs and end point modules. It is only available within a project context and cannot be ordered as a single standard product.
The GX1's final configuration depends on the end application. Some typical industrial applications include multi-CPU high speed video and image processing, supercomputing and virtualization. It comes with Express Switch or Express Fabric functionality. The GX1 offers a cost-effective PCIe Gen 3 switching solution via the CompactPCI Serial backplane.
