Some attempts are going on with AP7 series. It is not the processor mode that poses a problem but the memory limitation. Memory footprint is the fat issue. Despite the fact that AP7 series has MMU and allows external 16-bit SRAM for additional memory, experience shows that virtualization still remains a fairly big challenge. UC3 series have no MMU at all. Except for UC3A, no other series has extended memory support either. AFAIK, it is mostly a closed alley. Anitha
