Tool Description and Risk Analysis

AscendNPU IR contains the following binary tools.

**Table 1** AscendNPU IR description
Tool	Relative Path	Description	Risk Analysis	Reason for Retaining
bishengir-compile	bishengir/bin/bishengir-compile	Ascend high-level abstract compilation tool. It can compile AscendNPU IR into a binary file that can be executed on the Ascend AI Processor.	This low-risk tool can only be used to compile the IR for generating an executable binary file and no runtime information will be returned.	It is a basic binary tool set for AscendNPU IR.
bishengir-hivm-compile	bishengir/bin/bishengir-hivm-compile	HIVM IR compilation optimization tool. It can compile the HIVM dialect IR of AscendNPU IR into a binary file that can be executed on the Ascend AI Processor through automatic vectorization, memory allocation, and multi-pipeline synchronization.	This low-risk tool can only be used to compile the IR for generating an executable binary file and no runtime information will be returned.
hivmc	bishengir/bin/hivmc	HIVM IR compilation tool. It can compile the minimum set of HIVM dialect OP definitions of AscendNPU IR into a binary file that can be executed on the Ascend AI Processor.	This low-risk tool can only be used to compile the IR for generating an executable binary file and no runtime information will be returned.
bishengir-opt	bishengir/bin/bishengir-opt	Tool for converting, optimizing, and degrading AscendNPU IR. It processes AscendNPU IR and outputs a lower-level or optimized AscendNPU IR.	This low-risk tool can only be used to convert, optimize, and degrade IR and no runtime information will be returned.
