Radiation Hardened Computer Platform with Reconfigurable FGPAs
The Proton300k™ computer platform is a high performance radiation hardened processing solution that meets the challenges of the harsh space environment. Several advanced technologies are brought together in the Proton300k™ to provide industry leading performance, power, and radiation hardening. The Proton300k™ computer platform can accept several reconfigurable FPGAs to accommodate a wide variety of space applications.
Need
Commercial digital signal processors (DSPs) and FPGAs suffer from radiation effects in the space environment, particularly single event upsets (SEU) and single event functional interrupts (SEFI). Furthermore, traditional radiation hardened computer suppliers have struggled to deliver performance and user-programmability while maintaining radiation hardness. The Proton300K™ utilizes Space Micro’s patent-pending Time-Triple Modular Redundancy (TTMR™) and Hardened Core (H-Core™) technologies to solve the SEU and SEFI issues commonly encountered with DSPs and FPGAs.
Highlights
In addition to its radiation hardening, the Proton300k™ has a modular architecture, so that it can accommodate a number of FPGAs as well as various memory and communication bus options. Its low power requirements also make it ideal for a wide variety of space applications. SEU mitigation is handled with the on-board DSP. This mitigation can be turned on or off. This allows the utilization of the full power of the FPGAs during non-critical aspects of the mission, while mitigating SEUs during critical phases.
Applicability
With the capability to accept several reconfigurable FPGAs, the Proton300k™ can be customized to accommodate the needs of a variety of satellite and launch systems. This includes processing of image and sensor data, advanced algorithms, or many other applications in LEO or GEO orbits.
