Overview:
| CPU | TTA OISP |
| Data | Reconfigurable |
| Memory | Same width as data |
| Architecture | Von Neumann, technically your choice |
| Technology | Verlog |
| Status | Finished |
| Successor | None |
| Time period | July 2017? |
Problems:
The TTA OISP is the most used processor I have made, mainly because it is easy to make and reconfigure. Be aware that all computations will have to go through some sort of memory-mapped ALU.

An attempt to document the use of OISP in a prime finding hardware experiment. If I were to do it again, I would make a custom processor just for that purpose. OISCs are simple, but slow.
