This approach is implemented by rule set building, tree pattern matching and math expression transformation. 该方法通过建立数学规则库,对两个数学表达式进行树型模式匹配和算式变换来实现。
Improved Algorithm of Huffman Coding Based on Tree Pattern Matching(TPM) 哈夫曼编码的一种基于树型模式匹配的改进型算法
The relationship between machine description and code generation, and the technique of mapping RTL into object code by tree pattern matching are described in detail. 重点研究了机器描述与代码生成之间的关系、如何选用合适的中间表示进行目标机器指令系统的描述、树模式匹配的目标代码生成技术等。
This method is easier than tree pattern matching, and can be used in other DSP processors supporting parallel instructions. 这种方法比树模式匹配方法更容易实现,并适用于支持并行指令的其他DSP处理器。
Since the efficiency of tree pattern matching against a tree-structured database depends on the size of the pattern trees, it is essential to identify and eliminate the redundant nodes in the pattern and do so as quickly as possible. 在树形结构数据库上进行树模式匹配的效率取决于模式树的大小,因而尽快发现和删除模式中的冗余节点就显得十分的重要。
