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.
