Porting PIO C-code from ARM-7 to Nios II (SE1-board) + performance issue.

Hi all, I'm having a try at the moment to port my C-code from the arm-7 mcu, LPC-P2148 to Nios II, SE1-board , Cyclon-II, EP2C20F484C7. The arm-none-eabi-gcc compiler was used for the ARM-7 ...

NIOS II/e 0.15 MIPS/MHz

NIOS II/s 0.64 MIPS/MHz

NIOS II/f 1.13 MIPS/MHz
