Abstract
CCSDS has published widely recognized data
communication standard for space missions. This paper
discusses a custom streamlined implementation of the CCSDS
channel, frame and packet layers. Non essential features and
extra fields are omitted/not implemented from the packets and
frames. The stack is ported for two 32 bit controllers. One is
ARM7 based STR710 from STMicroelectronics and other is
80386 based, 386Ex from Intel. Both are candidates for a space
application protocol processor and therefore their performance
data is required, to evaluate protocol stack performance thus
assisting selection. Parameters compared are frame/packet
generation time, parsing time, throughput and application
memory footprint. Porting effort is also considered.
It is hard to select a controller when two different architectures
and tool chains are involved but this comparison may act as a
worthy parameter for decision making.
