| Abstract: | This paper introduces several mainstream programmable logic devices used in space electronics equipment.In consideration of particular characteristics of space environment,special approaches should be used when using FPGA in space.Functional Triple Modular Redundancy (FTMR) approach in FPGA design has been introduced to protect design from the SEU (Single Event Upset) induced by radiation.Examples of FTRM are given to demonstrate the effects of this approach. |
