Software in #radiation env ll
Notice there is mem #scrub rate calculation xls at this site. You can use it to cal how often to scrub mem based on radiation env, mem type/size, etc. idea is to avoid errors which are not correctable. Doesnt necessarilly mean single error since you may used…[Read more]
Software works in #radiation env
Good post from rsjaffe
NASA has a paper on radiation-hardened software. It describes three main tasks:
Regular monitoring of memory for errors then scrubbing out those errors,
robust error recovery mechanisms, and
the ability to reconfigure if something…[Read more]

#FPGA #TMR Tool
TMR (Triple Modular Redundancy) is widely used in #space electronics design. Xilinx provides TMRtool to auto generate TMR-ed design so you don’t have to manually implement it by tripling comb logics and putting in a voter.
Looks Actel provides another solution that its…[Read more]
