The chapter presents structural design of resilient architectureResilient architecture, describing all three areas of data handling: active zone where data processed, interfacing zone where data transfer between architecture elements, and passive—where data stored. ProcessorProcessor as it should be for resilient architectures is presented in full details—hardware schemes, instruction set, comparison with other processors used in the same area. Interfacing zone described with new communicative element so-called T-logic that “glue system together”. Passive zone, memory that is designed with extreme flexibility to fit all demands: reliabilityReliability of a system, performancePerformance and energy-saving. New system hardware element to manage resilience of functioning so called a Syndrome is introduced and explained. Its functioning within the system in concert with a new processor that best fit resilience of a system explained. Drawbacks of existing processors that market tries to procrastinate into the areas where safety criticality of functioning are discussed. Complete reconfiguration scenario for a proposed computer system is considered, explained and tested. Prototype system with required features of resilience is presented and explained.
