Moxie is an architecture. MoxieLite is one implementation of that architecture (non-pipelined, resource-light). Marin is a kind of SoC - the combination of the MoxieLite core along with various peripherals and controllers. http://github.com/atgreen/moxie-cores It is similar, in a way, to the Miklymist SoC, which uses an LM32 soft-core (and is supported by qemu). The Xilinx and Altera parts with Cortex-A9 cores are similar, except that that Cortex-A9 is an on-chip ASIC, instead of a soft SoC. AG
