Abstract:
An approach provides indirect addressing support for PIM. Indirect PIM commands include address translation information that allows memory modules to perform indirect addressing. Processing logic in a memory module processes an indirect PIM command and retrieves, from a first memory location, a virtual address of a second memory location. The processing logic calculates a corresponding physical address for the virtual address using the address translation information included with the indirect PIM command and retrieves, from the second memory location, a virtual address of a third memory location. This process is repeated any number of times until one or more indirection stop criteria are satisfied. The indirection stop criteria stop the process when work has been completed normally or to prevent errors. Implementations include the processing logic in the memory module working in cooperation with a memory controller to perform indirect addressing.
