Abstract: An apparatus includes a memory controller that includes logic to receive a first memory request having a first request type and a second memory request having a second request type. The apparatus also includes a scheduling unit that includes logic to schedule an order of the first and second memory requests for execution based upon a first parameter value and a second parameter value. The first parameter value corresponds to a utility and energy cost for the first memory request and the second parameter value corresponds to a utility and energy cost for the second memory request.

Abstract: Leveraging processing-in-memory (PIM) resources to expedite non-PIM instructions executed on a host is disclosed. In an implementation, a memory controller identifies a first write instruction to write first data to a first memory location, where the first write instruction is not a processing-in-memory (PIM) instruction. The memory controller then writes the first data to a first PIM register. Opportunistically, the memory controller moves the first data from the first PIM register to the first memory location. In another implementation, a memory controller identifies a first memory location associated with a first read instruction, where the first read instruction is not a processing-in-memory (PIM) instruction. The memory controller identifies that a PIM register is associated with the first memory location. The memory controller then reads, in response to the first read instruction, first data from the PIM register.
