Re: why startkit have no specific datasheet for its main chi

The device available on startKIT is A16. You can get the data sheet of the device from the following link: https://www.xmos.com/download/public/XS1-A16A-128-FB217-Datasheet%28X5719J%29.pdf On startKIT, one tile is used for debugging and the other tile is available for programming. So, you can use o...

whats the difference between XTAG and J-link ,I wanna to know may I use my J-link to debug startkit, I find it has xtag interface on the back side of startKIt board.

why startkit have no specific datasheet for its main chip ?

as the title:
why startkit have no specific datasheet for its main chip ?

1.for security consideration ?

2.for have no time to write a datasheet ?

if I want to use xmos chip to commercial project ,it may cause trouble when I deliver it from startkit to A8 or A16 dev

Re: How to get started with startKIT

It would be misleading to advertise it as a 16-core device while 8 of them are not (trivially) usable to the programmer. As I'd like to have a go at connecting a bunch of startkits together I'm definitely interested in how to "free up" the hidden tile. I assume if configured correctly it ...

Re: Doubt about xcore processor ?

Hi SUNROC1, Xmos is a hardware parallel architecture, i.e. when STM32F4xx is servicing an interrupt, the main program is completely stoped, while in XMOS you can dedicate a core to service a task when the main task is still executing. The main advantage in favour of XMOS, from my point of view, is ...

Doubt about xcore processor ?

1、xmos offical datasheet declare that its I/O speed can reach up to 60Mhz ,is this fast enough ? 2、STMicroelectronics declare its new stm32f43xx series IO speed up to 90MHZ 3、xcore per core only 125mhz ,but stm32f439 could reatch 180mhz , so there's room for improvement ,perhaps limit to 125mhz coul...

论坛在中国访问缓慢,希望改进

1、访问缓慢
2、登陆论坛后,经常掉线,得重复登陆
3、希望论坛能够显示图片,方便讨论
4、发帖时提交多次,网站来不及反应,会出现两个相同的帖子
