Xbox 360 has 3 core composition which can use 6 hardware threads (HWT).
The number is shaken at HWT.
| Core | HWT | Use |
|---|---|---|
| 0 | 0 | Use is impossible. System notice, Transformer port, Service. |
| 0 | 1 | Use is possible. Game main thread, GSE host, .NetCF. |
| 1 | 2 | Use is impossible. Asynchronous Xbox 360 content operation. |
| 1 | 3 | Use is possible. Xbox 360 guide, Dashboard. |
| 2 | 4 | Use is possible. Xbox Live market place download. |
| 2 | 5 | Use is possible. Xbox 360 guide, Dashboard. |
Thread.SetProcessorAffinity method is used for assignment of HWT.
However, since only assignment of the thread under execution can do this method now, it is necessary to specify it as the beginning of the entry point of a thread.
The technique of the multithread of C#/.NET can be used as it is.
