Semiconductor Multilayer Bus Memory Access Arbitration

The patent applies preliminary action by pre-defining process regions and candidate regions in the memory before tasks are executed. The operating system预先 allocates specific memory regions to different tasks and establishes arbitration rules in advance. When bus masters need to access memory, they follow the pre-established allocation scheme, which prevents competition before it occurs and eliminates the need for runtime arbitration, thus maintaining parallel processing capability while avoiding time loss from conflicts.

The patent implements self-service by enabling the operating system to automatically manage memory resource allocation and arbitration. The OS maintains a management table that tracks process regions and candidate regions, and automatically arbitrates memory access requests from multiple bus masters without requiring developer intervention. This automated self-management mechanism ensures reliable competition suppression while freeing developers from complex memory management tasks, thereby improving software development efficiency.

The patent applies segmentation by dividing the memory space into multiple candidate regions and allowing the operating system to dynamically allocate process regions from these segments. Each candidate region can be independently managed and assigned to different tasks based on their requirements. This segmentation approach provides flexible resource allocation while keeping the management structure organized and manageable, as the OS only needs to track regions rather than individual memory addresses, thus balancing adaptability with acceptable system complexity.
