SoC Design: When Network-On-Chip Meets Cache Coherency
Many people have heard of the term cache coherency, but do not fully understand the considerations for System-on-Chip (SoC) devices, especially those using Network-on-Chip (NoC). To understand the current issues, one must first grasp the role of cache in the memory hierarchy. Cache in Memory Hierarchy The CPU has relatively few extremely fast registers. The … Read more
