actually move the physical location of the TCM around. At the

place you put it, it will mask any underlying RAM from the

CPU so it is usually wise not to overlap any physical RAM with

the TCM. The TCM memory exists totally outside the MMU and will

override any MMU mappings.

the TCM.



Code executing inside the ITCM does not "see" any MMU mappings

and e.g. register accesses must be made to physical addresses.

The TCM memory can then be remapped to another address again using

the MMU, but notice that the TCM if often used in situations where

the MMU is turned off. To avoid confusion the current Linux

implementation will map the TCM 1 to 1 from physical to virtual

memory in the location specified by the machine.



TCM is used for a few things:
