METHODS AND SYSTEMS FOR MAPPING A PERIPHERAL FUNCTION ONTO A LEGACY MEMORY INTERFACE

摘要

A memory system includes a CPU that communicates commands and addresses to a main-memory module. The module includes a buffer circuit that relays commands and data between the CPU and the main memory. The memory module additionally includes an embedded processor that shares access to main memory in support of peripheral functionality, such as graphics processing, for improved overall system performance. The buffer circuit facilitates the communication of instructions and data between CPU and the peripheral processor in a manner that minimizes or eliminates the need to modify CPU, and consequently reduces practical barriers to the adoption of main-memory modules with integrated processing power.

1. A module, comprising:
a processor to receive data to be processed from a first memory on the module that is associated with a first aperture and to receive data to be processed from a second memory on the module that is associated with a second aperture; a memory interface configured to interface with a memory controller of a host system, the memory interface including a memory data interface, the host to provide the data to be processed to the memory controller for provision to the module via the memory interface, the module configurable to provide the processor with access to the first memory concurrent with the memory controller accessing the second memory, and the module configurable to provide the processor with access to the second memory concurrent with the memory controller accessing the first memory.
