Can anyone tell me with which attributes memory is handled in the Iyonix? I am trying to optimize some code for the Xscale by using the PLD assembler instruction. However until now without any affect. So I am examine whether all conditions for its usage are met. In detail: All is happening inside regular application space. Is this area of memory in general marked as buffered and cacheable (allocated by malloc in C)? Makes RISC OS on the Iyonix usage of the Xscale MMU (is it enabled)? Many thanks for any hints in advance.
