摘要： Systems or methods of the present disclosure may include a programmable logic device having a first portion of programmable elements configured to implement a user logic. The programmable logic device also includes a second portion of the programmable elements. The second portion is configured to implement an infrastructure processing unit (IPU) to enable the first portion of programmable elements to interface with a plurality of accelerator engines. The IPU is to receive a chained command to cause two or more accelerator engines of the plurality of accelerator engines to perform sequential operations on a data packet in response to the chained command.

摘要： The present disclosure is directed to enabling operation of a field programmable gate array (FPGA) while preventing application quiescence during FPGA reconfiguration. In embodiments of the disclosure, proxy agent firmware may enable downstream transactions (e.g., PCIe transactions) to be serviced during reconfiguration of the FPGA. Programmable logic states (e.g., PCIe configuration states or memory-mapped input/output (MMIO) states) are saved in memory and maintained by the proxy agent (via a management controller running the proxy agent). Once the FPGA is reconfigured, the state may be restored to the FPGA's programmable logic, and the FPGA may operate on the current state of the transactions.

摘要： In one embodiment, a hierarchical scheduling system including multiple scheduling layers with layer bypass is used to schedule items (e.g., corresponding to packets). This scheduling of items performed in one embodiment includes: propagating first items through the hierarchical scheduling system and updating scheduling information in each of the plurality of scheduling layers based on said propagated first items as said propagated first items propagate through the plurality of scheduling layers, and bypassing one or more scheduling layers of the plurality of scheduling layers for scheduling bypassing items and updating scheduling information in each of said bypassed one or more scheduling layers based on said bypassing items. In one embodiment, this method is performed by a particular machine. In one embodiment, the operations of propagating first items through the hierarchical scheduling system and bypassing one or more scheduling layers are done in parallel.
