Optimizing DDR Memory Subsystem Efficiency


The memory subsystem sits at the core of a System-on-Chip (SoC) platform and can make all the difference between a well-designed system meeting its performance requirements and a system that delivers poor performance, or even fails to operate correctly. State-of-the-art DDR memory controllers use advanced arbitration and scheduling policies to optimize DDR memory efficiency. At the same time, t... » read more

An Architecture Synthesis Platform For Rapidly Evolving SoC Designs


Modern System-on-Chip (SoC) architects are faced with a number of serious challenges. First, the number of Semiconductor Intellectual Property (IP) blocks in SoC designs is growing continuously and increasing design complexity. With IP design reuse becoming more common, the mixing and matching of IP components is further compounding design complexity. Second, sophisticated SoC applications are ... » read more
