TI-NSpire 情况各种 from omnimaga.org
本帖最后由 朔雪X忆 于 2011-1-15 15:40 编辑1. NS也有超频软件了 软件名字是Nover

Nover lets you play with 3 parameters:
* Base frequency: 27MHz or 114MHz-300MHz (by steps of 6) - default is 180MHz in all OSes
* Base/CPU ratio: x2-x254 (by steps of 2) - default is x2 in all OSes (x0 can be set but seems to be the ame as x2)
* CPU/AHB ratio: x1-x8 - default was x6 in OSes 1.x & 2.0, and is now x1 in OS 2.1
Base/CPU ratio cannot be improved
(but you can make your calculator 127 times slower if you want :p ).
Setting CPU/AHB ratio to x1 made my calculator around 2 times faster with time-consuming mathematical sequences calculations.
这里的超频只对ASM程序有效，对NSpire本身的Apps是无效的。 2. OS3.0 图泄

数据传感器厂商DataQuest™泄出的 OS3.0 图：
http://www.vernier.com/calc/ti-nspire/dataquest.html ns的超频是针对2.0os及以下的，2.1已经被官方超频了。
前几天还上过vernier的网站的，怎么就没发现os3.0的图..囧
不过泄露的部分只是传感器程序而已，我更加关心作为计算器的部分 本帖最后由 朔雪X忆 于 2011-1-15 16:10 编辑

和

都是关于超频的。
OS2.1也可超频，不过由于官方已经超过了，因此超频幅度会小。 3. NS自检出现SD卡项目的原因Link: http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=915
原型机是有SD卡的~貌似TI打算推出带SD卡的扩展坞了。
OTG Power Test???
和MP4的OTG一样吗？ 3. NS自检出现SD卡项目的原因Link: http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=915

法文看不懂……那个所谓的扩展坞，要是放到中国来卖肯定又要卖到几百……
os2.2前两天不是还有谣言吗？怎么os3.0都有截图了？
仍然期待3D作图和SDK…… 还有，那个Lab Cradle造型好霸气……

根据那个网站的跳转，那个Lab Cradle要价234美刀。。。 2.1被官方超频了？哇。。 不过OS1.7怎么可能能运行第三方开发的软件（超频软件）呢？ 这比ebay上卖的ns也便宜不了多少……
回imath，您难道不知道ndless支持1.7了。么。。不过好像的确在论坛没提过。。 超频软件补充:

OS 1.1-2.0 default speeds:
- Base frequency: 180 MHz
- CPU frequency: 90 MHz
- AHB bus frequency: 15 MHz
The max possible after using Nover:
- Base frequency: 180 MHz
- CPU frequency: 90 MHz
- AHB bus frequency: 45 MHz
This almost doubles the execution speed of TI-Nspire BASIC and OS functions.
However, OS 2.1 is different. Here are its default settings:
- Base frequency: 240 MHz
- CPU frequency: 120 MHz
- AHB bus frequency: 60 MHz
TI made that OS compatible with faster speeds to accommodate the OS's slower execution speed. At this configuration, the OS appears to run slightly faster. The removal of the limitation, however, allows critor's program to set the speed of the TI-OS even faster than in 2.0.1 or lower, though:
- Base frequency: 300 MHz
- CPU frequency: 150 MHz
- AHB bus frequency: 75 MHz
In other words, this would be between twice and three times faster than OS 2.0 running without Nover's support! However, remember that OS 2.1 has some downsides, such as its larger file size (although this can be solved with a previous program we posted news about) and your machine needs Boot2 1.4, not 1.1, else OS 2.1 will not start-up on it. In other words, if your TI-Nspire came with OS 1.1, make sure to install OS 1.4 through 2.0.1 on it and start it at least once prior installing OS 2.1!
Anyway, if you want to try the program, you can download it here! Be careful to which settings you choose, though, especially on older OSes, else, use it at your own risk! 2. OS3.0 图泄
