Basic typing of multi-bit applications in the structure of modern software

The author considers a special class of portable applications: multi-bit applications, which are special applications that can operate in several selected microprocessor modes in extreme environmental conditions. In a technical aspect, this effect allows, through the use of logical isolation of damaged parts of the microprocessor, to perform a microprocessor mode change in most cases without data loss, or with minimal losses associated with a decrease in calculation accuracy and the amount of accumulated damage in the microprocessor. In the presence of such a microprocessor, which is primarily operated in extreme environmental conditions, such as outer space, special applications are needed that can use the technical capabilities of modified microprocessors. The article describes the place of this class of applications in terms of existing approaches.
