HiAsm is a high-level assembly language for x86 processors. It features a simplified syntax and type safety while allowing direct access to CPU functions, making it suitable for writing high-performance system-level software such as drivers or operating systems. HiAsm was designed as an alternative to traditional assembly languages that could leverage the capabilities of modern processors without sacrificing readability or maintainability. The language can be used with Macro Assembler, a part of MASM (Microsoft Macro Assembler), and other relevant tools in the Microsoft ecosystem.
