Abstract

Microcode is used to facilitate new technologies in Intel CPU designs. A critical requirement is that new designs be backwardly compatible with legacy code when new functionalities are disabled. Several features distinguish microcode from other software systems, such as: interaction with the external environment, sensitivity to exceptions, and the complexity of instructions. This work describes the ideas behind MICROFORMAL, a technology for fully automated formal verification of functional backward compatibility of microcode.
