4fb9d08492 The incoming memory address request (1) is translated into the table (2) and each memory address will be associated with an ID (4) that represents the ID of the local node to which the memory adders is related. The translated base register contains the base address of the transactions forwarded through the existing non-transparent bridge using the corresponding BAR.

It must be understood that the inventions disclosed and taught herein are susceptible to numerous and various modifications and alternative forms. PCIe is not designed to support efficient network topologies.There is a need for a PCIe non-transparent bridging that is expressly designed for scalability and networking applications that can be combined with the transparent PCIe switching technology. Each x86-based PC connects to one down-stream port of the Multi-port PCIe switch via the Non-transparent Bridge (NTB) port of the IDT PES24NT3 PCIe inter-domain switch. BAR4 and BARS are combined together in order to provide 64 bit memory addressing, a prefetchable memory configuration with at least 16 MB (mega byte) of memory aperture window.
Each of this group of ports is composed exclusively of one single root complex port (upstream port in the PCIe switch convention) and some (at least one) transparent (downstream) ports. The software is divided into three layers. The introduction of the non-transparent bridging enables the creation of an interconnection network based on PCIe with distributed IO sharing. The mapping engine (3) has two major components: the PCIe to dNTB bus mapping core (4) that performs the memory mapping and packets communication translating the PCIe into the dNTB bus, and the dNTB to PCIe bus mapping core (5) that performs the memory mapping from the global shared memory address space of the dNTB into PCIe interface enabling the communication between the dNTB fabric and the PCIe interface. Depending on the architecture, the PCIe card either connects directly to the processor's PCIe bus, or through a Transparent Port (TP) on a PCIe Switch. Similarly, the local CPU will enumerate through Bridge E and F (both virtual bridges within the switch) and discover the endpoint Y, but will not attempt to discover elements beyond Bridge D. 3a shows in one preferred embodiment the switch core configuration where an embedded CPU (1) is used for the PCIe enumeration of the local EPs.FIG.
