  TI RTOS Kernel has no concept of memory mapping. Everything runs in physical memory

  This is very common: MMUs are expensive, take up lots of silicon real estate, consume power, produce heat and use lots of memory

  Yes it takes memory to map memory. It's not uncommon for memory protected kernels to have a gig of page tables. That's why the Linux kernel mailing list is so full of discussions about reducing memory fragmentation: two discontinuous memory mappings will consume two page table entries

  I do embedded and drivers because my clients are happy to give me all the time and money I require to get all the bugs out. My GUI client's were never that way
