Cluster Memory Broadcast Control for Multi-PE Data Access

The patent segments the memory access control by implementing separate request queues for different processing elements (PEs) within a cluster. Each PE has its own request queue that is independently managed by the cluster controller, allowing simultaneous request handling without conflicts. This segmentation eliminates the need for synchronization between PEs while maintaining orderly access to the shared cluster memory.

The patent implements preliminary action by establishing a predefined request queue structure for each processing element before data transfer begins. The cluster controller pre-allocates and manages separate queues for each PE, so when multiple PEs access the shared cluster memory simultaneously, their requests are already organized in dedicated queues. This preliminary organization prevents data collisions while maintaining high transfer speeds, ensuring both speed and reliability.

The patent implements self-service by enabling each processing element to independently manage its own memory access requests through its dedicated request queue. The cluster controller automatically retrieves requests from these queues and manages the actual memory access operations. This self-service mechanism allows PEs to operate independently without synchronization overhead, reducing energy consumption while the automated queue management handles the coordination complexity, effectively decoupling independence from complexity.
