CATLASS DSL
CATLASS DSL 是 CATLASS 的 Python 前端。它在 AscendNPU-IR 的基础上构建 TLA Dialect，将 Python 中描述的 TLA 操作降级为 MLIR，并由 AscendNPU-IR 工具链编译为可执行的核函数产物。
目前，CATLASS DSL 主要对 TLA 框架提供了DSL封装，可以使用tla.make_tensor等API来描述TLA操作，完成算子的实现。未来，我们将继续扩展CATLASS DSL，在全量支持TLA tensor抽象接口、矩阵向量计算等接口的基础之上，进行类似CATLASS 模板的封装，实现对齐CATLASS C++模板算子的开发体验。
