Abstract

The purpose of this paper is to describe a set of DDR3 SDRAM interference estimation cost functions. The arbitration system of the SDRAM controller heavily impact the interference analysis. In this work, three arbitration are considered, corresponding to the situations where the accessed memory address belongs to the same block address, different memory banks and different rows. The aim of these functions is to estimate the instructions interference overhead may suffer when concurrently accessing these three logical addresses in a SDRAM saturation context. To develop these interference expressions, specific measurement systems, micro-benchmarks and theory on SDRAM controllers have been used.
