Thesis (MScEng)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: For space designs, just as for terrestrial applications, the appetite for more computing
power is virtually insatiable. Further, like portable applications, space use implies severe
power constraints. Among currently available commercial processors, the PowerPC family
ranks high in Million Instructions Per Second (MIPS) per watt, but its suitability for space
applications outside low-earth orbits (LEOs) may be limited by the radiation environment,
particularly single ev nt effects (SEE).
This thesis covers the feasibility of using the PowerPC 603e™ processor for LEO satellite
applications. The PowerPC architecture is well established with an excellent roadmap,
which makes for a baseline microprocessor with long-term availability and excellent software
support. The evaluation board design leverages Commercial Off-The-Shelf (COTS)
technologies, allowing early integration and test. It provides a clear path to upgrades and
provides a high performance platform to suit multiple missions. / AFRIKAANSE OPSOMMING: Die soeke na rekenaars met hoer werkverrigting sal nooit ophou rue. Dit geld vir beide
rekenaars op aarde as satelliet aanboord rekenaars. Rekenaars vir ruimte gebruik word ook
streng drywingsbeperkings opgele. Die PowerPC familie vergelyk baie goed met ander
verwerkers, maar hul bruikbaarheid vir ruimte toepassings kan dalk beperk word tot lae
wentelbane waar die ruimte radiasie omgewing meer toeganklik is.
Die skrywe behandel die bruikbaarheid van die PowerPC 603e verwerker vir lae wentelbaan
satelliet gebruik. Die welgestelde argitektuur, bekombaarheid en uitstekende sagte- _
ware ondersteuning verseker 'n standvastige fondasie. Kornmersiele komponente het
voorkeur geniet in die hardeware ontwerp wat spoedige ontwikkeling sowel as aanpasbaarheid
verseker. Die ontwerp bied 'n hoe werkverrigting en maklik opgradeerbare oplossing
vir 'n groot verskeidenheid gebruike.
