We have built and tested a Single Event Upset (SEU) tolerant computer (STC) based on the MIPS Inc. R3000 processor. Testing in a proton environment is ongoing. The design of this computer was postulated in previous work and based upon extensive radiation effects testing performed by Lawrence Livermore National Laboratory (LLNL). This computer is based entirely on commercially available parts. The purpose of these tests is to demonstrate the capability of using non-radiation hardened parts in an SEU environment, in this case Low Earth Orbit (LEO), with upset mitigation through fault tolerant hardware and software design methodologies. The hardware and software designs are described in detail, the test setup and test parameters are given and test results are presented.
