The GNU and Linux successes have proven that this development mode is successful for software, we want to prove it is also suitable for hardware development.<br><br></b></font><font color="000088"size=+1><b>2.What help do we want?<br></b></font><font ><b><br>Currently, this is a very small team. There is only one main developer, and one documentation person. We can not imagine that such a small team can manage to create this entire system without additional design and testing help. So any kind of help is welcomed. If you are interest in this, please contact <a href="mailto:shengyu_shen@hotmail.com"></a><br><br>

First, this team is particularly weak in the design of cache and memory controllers, so we are eager for help in this field.<br><br>
|

|
|
Second,Help to test the core, both in the simulator or on an actual FPGA board.<br><br>
|
| 17 |
|
|
Third, help to port uclinux or ECOS to nnARM<br><br></b></font>

<font ><b><br>Currently, this core can fully support ARMv4T ISA<br><br>
