Abstract: This paper presents a realizable architecture of PC control software. The architecture is based on uncorrelated instructions, we take the instruction decoding off the system. After dynamically configuring and encoding, those instructions can be dynamically recombined and invoked at run time. This design of uncorrelated instructions will greatly improve the efficiency of software development and will also do some help to the expandability and maintainability of the application system.

Key words: uncorrelated instruction, software, architecture, protocol
