一种记忆感知的高级综合算法
A Memory Aware High Level Synthesis Too
摘要:
本文介绍了一种新的方法,在数据密集型应用的高级综合中考虑存储器结构和存储器映射。我们将内存映射形式化为一组用于合成的约束,并定义了一个内存约束图和一个可访问性标准用于调度步骤。我们使用内存映射文件将这些内存约束包含在HLS工具GAUT中。在GAUT的帮助下,可以探索各种解决方案,并在时间,功耗和面积之间取得良好的平衡。
英文摘要:
We introduce a new approach to take into account the memory architecture and the memory mapping in High- Level Synthesis for data intensive applications. We formalize the memory mapping as a set of constraints for the synthesis, and defined a Memory Constraint Graph and an accessibility criterion to be used in the scheduling step. We use a memory mapping file to include those memory constraints in our HLS tool GAUT. It is possible, with the help of GAUT, to explore a wide range of solutions, and to reach a good tradeoff between time, power-consumption, and area.
