Hi all,
I am new in this forum and I want to know if the OR1K processor supports the little endian?? Thx, Moktar. |

Hi Moktar, The OpenRISC 1000 architecture specification allows for both little-endian and bit-endian implementations. The only implementation currently available, the OR1200, is a big-endian implementation. Various people have experimented with little-endian versions, but they aren't in the OpenCores repository. The GNU tool chain is currently only big-endian. There is some little-endian support in binutils, but as far as I am aware it has never been tested. HTH Jeremy |

Hi Jeremy,
Thank you for your reply. I used the simulator OVPsim to simulate the OR1K processor. I also tried to change the endianness but I can not find a solution. Thx, Mokhtar. |
