Hi,

have you already checked, what code is generated by the compiler (e.g. in the disassembly window) ? Especially in the debug version the compiler produces a lot of code. For the loop itself and the IORD_DIRECT32 access it is easily possible that 10-15 instructions are generated. So I think it is not a slow access to the sram which makes this code slow, it is the number of instructions which are generated. The release version should be faster.
