IP Core Source Code
|
| 61 |
|
|
----------------------------
|
| 62 |
|
|
The IP Core is written by verilog-HDL. The source code is Vendor independent.
|
| 63 |
|
|
does not require any Vendor specific module.
|
| 64 |
|
|
|
| 65 |
|
|
Simulation
|
| 66 |
|
|
----------------------------
|
| 67 |
|
|
scenario directory contains simple rendering bench.
|
| 68 |
|
|
the rendering result is converted to bmp file.
|
| 69 |
|
|
|
| 70 |
|
|

|
FPGA Sample Implementation
|
| 73 |
|
|
----------------------------
|
| 74 |
|
|
FPGA system implementation sample is available.
|
| 75 |
|
|
The target board is DE0.
|
| 76 |
|
|
The project data is tested on Quartus II Version 13.1
|
| 77 |
|
|
