The Desyre project couples a reconfigurable substrate with runtime-system software support in such a manner that the medical system-on-a-chip can adapt on demand to various types and densities of faults, system constraints, and application requirements.

Triple-Modular-Redundancy (TMR) systems compare the output of three identical modules and then trusts the “majority vote.” Desyre systems requires 46% less chip area and 28% less energy to achieve the same tolerance to transient faults and the same performance as a typical TMR technology.

To counter increasing fault rates and reduce power, the hybrid Desyre approach confirms that interchangeable processing cores are handling sub-tasks correctly and efficiently, while transferring tasks from one core to other idling cores when a malfunction is diagnosed.

When looking at permanent faults and comparing the Desyre technology with a core-redundant system of the same area, Desyre reduces the number of failures (due to permanent faults) in a billion device hours (FIT) by a factor of 9.
