The XY Memory is a feature commonly found in DSP processors to increase the DSP performance. The XY component allows a ARC processor to implicitly load source operands and store results into a closely coupled memory using a single instruction. Add XY memory for ARC EM9D/EM11D processors including em_starterkit, em_starterkit_em11d. emsdp_em9d, nsim_em, iotdk. Signed-off-by: Siyuan Cheng <siyuanc@synopsys.com>
