What is the difference between a cross assembler and a meta assembler?

A cross assembler is a tool that translates assembly language code written for one architecture into machine code for a different architecture, enabling development on a host system that differs from the target system. In contrast, a meta assembler is a higher-level tool that generates assembly code from a more abstract representation, often allowing for platform independence and easier management of complex assembly code across multiple architectures. Essentially, cross assemblers focus on architecture compatibility, while meta assemblers emphasize code generation and abstraction.
