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

Many thanks for the upgrade info although the answer is not good for me because I need at least the performance of an ARM-7. Do you think a Nios II/s or Nios II/f CPU is able to perform like a ARM-7 CPU ? Also, as far as I know, these Nios II CPU's are only useable with a special licence ? Too bad for me and it looks to me to redesign my project completely.

Concerning question B): This "problem" is fixed, I configured via SOPC Builder a PIO with extra input and output channel. The ported Statemant:

if (!( IORD_ALTERA_AVALON_PIO_DATA(PIO_0_BASE) & 0x00010000 ))

is now working fine ( only to slow :confused: )

Many thanks and regards.
