Now HLS has absorbed much research attention in IC-CAD field. In HLS, algorithms represented by algorithm description language are transformed into hardware structure description consisted of resisters and transfers. In the transforming process, synthesis of datapath is a core. The other works is based on it. And in the synthesis of datapath, operation scheduling, functional unit allocation and binding all are NP-Completeness problems. The structure of their solution space is not known well. If we must find a global optimum solution, we can only use exhaustion. This way needs too much computation for VLSI synthesis, and is impractical in Industry. So usually heuristic algorithms are used to search suboptimum solution.

因此HLS成为国际IC-CAD学界的一个热门，它把算法描述语言表达的算法转换为用寄存器、传输器描述的硬件结构，其中以数据通路的综合为主体，其余工作皆以此为基础；而在数据通路综合中，操作调度、功能单元分配、连线等均属NP问题，目前该问题的解空间尚未充分了解，如要求得最优解，只有采取穷举搜索法，对于大规模集成电路而言运算量太大，工业中无法承受，故通常都采用启发算法求次优解。
