Programmable, scalable, and performant virtual-to-physical address translation for remote direct memory access (RDMA) and other protocols

An integrated circuit (IC), comprising:

• a data processing pipeline configured to process a data object, wherein the data processing pipeline multiple processing stages and memory comprising a programmable access request table, and wherein a first one of the processing stages comprises:
• memory access request construction logic configured to construct a memory access request to obtain additional data for the data object, wherein the memory access request comprises an operational code that specifies a translation mode for the memory access request;
• first translation logic configured to retrieve translation data from the programmable access request table based on information contained in the memory access request, retrieves the additional data based on the translation mode and the translation data, and returns the additional data to the memory access request construction logic;
• and
• an instruction processor configured to process the data object based on the additional data.

A system, comprising:

• a data processing pipeline comprising multiple processing stages, each processing stage comprising translation logic configured to retrieve information from a programmable access request table based on information contained in a memory access request, and perform one or more of the following based on a translation mode specified in an operational code of the memory access request:
• translate a virtual address of the memory access request to a physical address based on the information retrieved from the programmable access request table, retrieve data based on the physical address, and provide the data in a response to the memory access request;
• and
• retrieve information regarding a memory region determined from the information retrieved from the programmable access request table, and provide the information regarding the memory region in the response to the memory access request.
