Buffer management within SLS (simple load store) apertures for inter-endpoint communication in advanced switching fabric

摘要

A single copy memory sharing scheme between multiple endpoints in an interconnect architecture may use a buffer management method in an advanced switching fabric having multiple endpoints that divides a simple load and store memory aperture into a buffer descriptor and at least one data buffer, provides offset addressing in the buffer descriptor, and accesses the buffer descriptor by more than one endpoint to allow direct memory access with multiple endpoints in a simple load and store memory aperture. An apparatus may have a memory, and a device associated with the memory, the device to divide the memory into a buffer descriptor and at least one data buffer, and to store offset address information in the buffer descriptor such that another device can access a data buffer in the memory.
