Title: ATOMIC MEMORY OPERATION
Abstract:
An atomic memory operation system comprises a memory fabric coupling a receiving node and a sending node. The memory fabric executes an atomic memory operation by identifying a control word of a ring buffer using a memory address of the memory operation. The memory fabric then retrieves a tail index from the control word, wherein the tail index indicates a position in a ring buffer, and inserts a memory word in the ring buffer at the position indicated by the tail index, wherein the memory word corresponds to the memory operation. Finally, the memory fabric updates the tail index in the control word to point to a next slot in the ring buffer.
