+# Ascend CANN Parser
+
+Ascend CANN Parser (Parser for short) works with the TF_Adapter, ATC, and IR graph composition tools. By using these tools, developers can easily convert the algorithm representation of third-party frameworks into Ascend IRs, making full use of the excellent computing capability of Ascend AI Processors.
