That is probably too early. Most of the current generation FPGA uses EZ-USB FX2LP (high speed USB). Interestingly the limit for the FX2LP is the slow 8051 MCU core, so it is rather a intelligent peripheral controller with a slow MCU core but not a real high speed USB 2.0 MCU. In the case of EZ-USB FX3, it now comes with a 200MHz ARM926EJS core, quite good, but still not a real super-speed USB MCU since that is still too slow compared to 5Gbps USB 3.0. http://www.edn.com/article/517788-USB_3_0_controller_embeds_microcontroller= _for_customized_applications.php On the other hand, even though I have bought two USB 3.0 external hard disks, none of my PCs come with USB 3.0 host controller (XHCI), so I do not know how good USB 3.0 is. --=20 Xiaofan --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
