Systems and methods for accessing storage-as-memory

A method performed by a hardware element of a processor, the method comprising:

• receiving, at a system agent implemented in a field programmable gate array (FPGA), a memory instruction from a hardware processor over a coherent interconnect link;
• translating a memory address in the memory instruction to identify a memory location managed by the system agent, the memory location part of a storage device communicatively coupled to the FPGA;
• executing the memory instruction;
• providing a confirmation of the memory instruction execution to the hardware processor;
• and retrieving data stored in the memory from across a high-speed serial interface.

A system comprising:

• a microprocessor comprising a microprocessor system agent;
• an accelerator system comprising:
• a system agent to process memory access requests received from the microprocessor system agent across a communications link, wherein the system agent and communications link are in a coherency domain of the microprocessor;
• a memory controller communicatively coupled to the system agent;
• and
• a high speed serial interface to link the system agent with a storage system;
• and
• a storage device connected to the accelerator system by the high speed serial interface;
• wherein the system agent is to process the memory access requests by translating addresses in the memory access requests to addresses of the storage system and accessing data at the addresses of the storage system through the high-speed serial interface.
