Is there a right place to ask some improvements/features for next Nuvoton SiP?
The one feature I am really missing is a simple additional MCU core (like 8051/Cortex-M0) to offload hard real-time tasks from ARM926 core. I.e. ARM9 runs networking and HMI tasks (possible Linux) and small 8051 core run fast GPIO handling, encoder processing and so on. Many competitors already implemented some kind of "slave MCU core" for industrial applications.
Another big miss of NUC970 is a very weak DMA controller. N9H26 and NUC980 are much better in that aspect, but lacks other important features.
Hope my feedback will help Nuvoton stuffs to find best direction for future development.
