Design and Develop Efficient Arbitration Technique to Handle the Multiple Refresh Requests in Multi-Processor SoC

Emerging memory technologies, such as Gain Cell-embedded Dynamic Random Access Memory (GC-eDRAM), play an essential part in the process of improving the overall performance of current multi-processor systems. GC-eDRAM, on the other hand, has its own set of distinct issues, particularly with regard to refresh operations. The number of cores and threads in contemporary processors continues to expand, which in turn leads to an increase in the number of concurrent refresh requests. This might cause contention, which in turn can lead to a possible performance decrease. In this article, we present an efficient arbitration method that was developed in order to precisely address the issues that are associated with numerous requests for a refresh in GC-eDRAM. This method takes use of the inherent parallelism of GC-eDRAM modules to make it possible to execute simultaneous refresh operations. As a result, contention is effectively reduced, and the overall performance of the system is improved. We provide a new arbitration method that prioritizes the pending refresh requests according to their level of urgency and optimizes the allocation of GC-eDRAM resources in order to guarantee that refresh operations are carried out in an effective manner. Our method modifies the arbitration priority in a dynamic manner according to the characteristics of the active workload. These characteristics include the request arrival rate, memory access patterns, and data location, among other considerations
