Highly Reliable Microprocessor
The reliability of electronic systems is a current issue and it is extremely important for critical systems.
In particular, in space applications, the electronics suffer from radiation and circuit damage.
The research activity focused on the development of systems for use in space missions and it has led to the design and implementation of a programmable rad-hard and fault-tolerant device.
The Hirempro project is a redundant processor implemented in MicroSemi’s Rad-Hard FPGA, the multiprocessor architecture allows you to use turned off processors as spare parts to replace processors that can suffer permanent failures due to radiations or other causes.
The redundant processor uses a TMR configuration with cold spare processors.
Replacement of damaged processors takes place automatically and transparently without interruption of processing.
Replacement processors are reduced if permanent failures occur; so the degradation of the system is progressive!
We have evidence of the gradual damage of the system and we can take appropriate action when the device is at the end of life. The processor can not stop working unexpectedly.
Redundant microcontroller equipped with a spare processing units.
Fault tolerant device based on multiprocessor patented at European level.
Microcontroller suitable for real-time systems.
Implemented in FPGA, even in Rad-Hard version.
Possibility to realize ASIC with RHBD circuits in collaboration with partner companies.
Innovative device able to overcome temporary failures (eg SEU, SET) and permanent failures (eg for TID) occurring in processor circuits.
Possibility to develop rugged boards suitable for environmental conditions of particular severity (for temperature, humidity, saline fog, vibrations, electromagnetic disturbances, radiation).
Possibility to produce systems with space, avionics, military certifications / qualifications.
Critical control systems in space, avionics, military, industrial, medical sector; non-maintenanceable systems.
This project is developed thanks to the financial support of the FESR funds.
