* Description
|

|
|
******************************************
|
| 29 |
|
|
The TosNet MicroBlaze peripheral provides an implementation of the TosNet
|
| 30 |
|
|
core, interfaced to the MicroBlaze PLB bus, along with a software driver
|
| 31 |
|
|
to support the functionality.
|
| 32 |
|
|
|

|
|
|

******************************************
|
| 35 |
|
|
* Installation
|
| 36 |
|
|
******************************************
|
| 37 |
|
|
Copy the contents of the 'drivers' and 'pcores' folders to an EDK peripheral
|
| 38 |
|
|
repository, preserving the original folder structure.
|
| 39 |
|
|
|
| 40 |
|
|
For instance:
|
| 41 |
|
|
c:\XilinxEDKRepository\MyProcessorIPLib\pcores\tosnet_v3_20_a
|
| 42 |
|
|
c:\XilinxEDKRepository\MyProcessorIPLib\drivers\tosnet_v3_20_a
|
| 43 |
|
|
|
| 44 |
|
|
You should now have access to the TosNet core from within EDKs IP Library.

|
|
1. Add the TosNet component to your design.
|
| 51 |
|
|
|
| 52 |
|
|
2. Make 'sig_in' and 'sig_out' external, and connect these to your
|
| 53 |
|
|
transmission components.
|
| 54 |
|
|
|
| 55 |
|
|
3. Connect 'clk_50M' to a 50 MHz clock signal.
|
| 56 |
|
|
|
| 57 |
|
|
4. Connect the 'sync_strobe' and 'system_halt' interrupt signals to an
|
| 58 |
|
|
interrupt controller, if necessary.
|
| 59 |
|
|
|
| 60 |
|
|
5. Connect the TosNet component to the PLB bus.
|
| 61 |
|
|
|
| 62 |
|
|
6. Configure the TosNet component to your likings ('Configure IP').
|
| 63 |
|
|
Important settings are the 'C_NODE_ID' and 'C_REG_ENABLE', that
|
| 64 |
|
|
configure the node id and register enables, respectively.
|
| 65 |
|
|
|
| 66 |
|
|
7. Generate addresses for the memory and register spaces. The memory space
|
| 67 |
|
|
needs 8 kB, the register space needs 40 B (in both cases, larger spaces
|
| 68 |
|
|
of course work fine too).
|
| 69 |
|
|
|
| 70 |
|
|
8. Done!

******************************************
|
| 74 |
|
|
* Usage, SDK
|
| 75 |
|
|
******************************************
|
| 76 |
|
|
1. Make sure that SDK is using the TosNet driver for the TosNet component.
|
| 77 |
|
|
|
| 78 |
|
|
2. Initialize a TosNet structure.
|
| 79 |
|
|
|
| 80 |
|
|
3. Use the API described in 'tosnet.h' to access the TosNet component.

|
|
* Important notes
|
| 85 |
|
|
******************************************
|
| 86 |
|
|
The MicroBlaze peripheral uses the exact same source files as the standard
|
| 87 |
|
|
TosNet component. This also goes for the BlockRAM and FIFO cores. The cores
|
| 88 |
|
|
delivered with the peripheral are created for the xc6slx16,csg234 device.
|
| 89 |
|
|
|
| 90 |
|
|
If you need to use the peripheral with other devices, you may have to
|
| 91 |
|
|
recreate the cores, using the settings described in the readme in the
|
| 92 |
|
|
'pcores\tosnet_v3_20_a\netlist' folder.
