Abstract: Approaches for configuring programmable resources of a programmable IC are disclosed. A first set of configuration data is loaded using a configuration port of the programmable IC, which also includes input/output (I/O) ports. Programmable resources are configured according to the first set of configuration data to implement a master data link circuit and at least one slave data link circuit. The master data link circuit includes a hardwired communication circuit, and a set of the programmable resources arranged to form a communication control circuit configured to control the communication circuit to provide a data link for communicating data via one of the I/O ports. A second set of configuration data is loaded using the master data link circuit. Programmable resources of the programmable IC are configured according to the second set of configuration data to implement a logic circuit configured to communicate data via the slave data link circuit.

Abstract: A method and a system for transparently overlaying a logical transport network over an existing physical transport network is disclosed. The system designates a virtual channel located in a first transaction layer of a network conforming to a first network protocol. The system assembles a transaction layer packet in a second logical transaction layer of a second network protocol that is also recognizable by the first transaction layer. The system transfers the transaction layer packet from the second transaction layer to the virtual channel. The system transmits the transaction layer packet over the first transaction layer using the designated virtual channel over the network.

Abstract: A method for providing access by a virtual context to a physical instance includes receiving a request to access a physical instance of a plurality of physical instances of a hardware resource of a device. The request is associated with a virtual machine of a plurality of virtual machines. The method next determines that one of the physical instances is available, and assigns a virtual context associated with the virtual machine to access the one of the physical instances when the one of the physical instances is available. The assigning comprises retrieving the virtual context from a memory of the device and loading the virtual context into the one of the physical instances. The method then stores the virtual context in the memory after the one of the physical instances is accessed by the virtual context.
