怎么通过GPIF II在Slave SelectMap中配置FPGA

你好，
可以在从属选择图中配置FPGA。但我们没有这样的例子。GPIF需要改变。
你可以参考这个例子，8216-设计一个GPIF II主接口CyPress半导体，其中FX3被配置为一个主机，并与一个奴隶进行数据传输。
当做，

  Hi,
 
It is possible to configure the FPGA in slave selectmap. But we do not have any example as such for this. The GPIF needs to be changed.
 
You can refer this example AN87216 - Designing a GPIF II Master Interface | Cypress Semiconductor where Fx3 is configured as a master and does data transfer with a slave.

谢谢你的回答。

  Thank You for Your answer.

如何使用并行配置？我可以使用CYU3PGPIOSLoSeStEValk来控制连接到CCK和FPGA的8个数据引脚的GPIOS吗？CCLK将足以传输数据吗？8个数据引脚可以同时更新值？函数CUU3PGPIOSLISESET值会以不确定的速度运行，会导致时序问题吗？

  how can I use parallel configuration? Can I use CyU3PGpioSimpleSetValue to control the GPIOs connected to CCLK and 8 data pins of the FPGA? CCLK will be good enough to tranfer data? 8 data pins can update value at the same time? will the function CyU3PGpioSimpleSetValue run with an uncertain speed that causes the timing problems?

至于我的理解，在配置示例AN848 68中，配置数据在发送VEDER命令之前完全存储在FX3上。一些FPGA有少量的配置数据，因此可以存储。FPGA I的配置数据达到2.7M字节。FX3的RAM是否足以容纳数据？如果没有，有什么解决办法吗？

  As to my understanding, In the configuration example AN84868, the configuration data are entirely stored at the FX3 before the vender command is sent. Some FPGA have a small volumn of configruation data and therefore can be stored. The configruation data of the FPGA I use achieves 2.7M Bytes. Is the ram of FX3 large enough to hold the data? If not, is there any solution?
