来自嵌入式消费领域的应用对SoC基础设施，即互连和存储器提出了具有挑战性的要求。具体地说，视频应用需要大存储容量和高带宽，而数据访问可能不规律。用于实现这些应用的SoC体系结构通常包含处理元件的异类集合，并且使用到片外DRAM的单个接口，以便以低成本提供所需的存储容量。为了获得访问存储器所需的带宽和延迟，需要适当地集成互连和存储器架构。应用需求以及访问存储器的特征和约束是NoC设计的关键输入。未来的存储器技术可能会通过提供高带宽存储器访问(可能通过多个存储器接口)而导致范式转变。
Applications from the embedded consumer domain put challenging requirements on SoC infrastructures, i.e. interconnect and memory. Specifically, video applications demand large storage capacity and high bandwidth while data accesses can be irregular. The SoC architectures used for implementing these applications typically contain a heterogeneous collection of processing elements and use a single interface to off-chip DRAM in order to provide the required storage capacity at a low cost. Proper integration of interconnect and memory architecture is required to achieve the required bandwidths and latencies for accessing memory. The application requirements as well as the characteristics and constraints for accessing memory are key inputs for NoC design. Future memory technologies may cause a paradigm shift by offering high-bandwidth memory access, possibly via multiple memory interfaces.
