I am looking for a usb 3.0 controller chip set into which I can dump my data of 8 bit or 16 bit -byte data at 36 Mhz/72 Mhz/144Mhz/ 148.5Mhz, clock speed. In order to be sent to PC's system memory through a USB bus in real time, there should be a good size of internal buffer(memory) of at least 8K Bytes in the USB controller.

Hi,
You can use FX3 for your application.
Please find FX3 datasheet at the following location:
http://www.cypress.com/?rID=50120
FX3 has 512KB of RAM in it.
It has a GPIF II to interface with any parallel interface. You can operate this interface at 36 Mhz/72 Mhz without any issue. The maximum clock that this interface operates is 100MHz.
Let me know if you need any more details regarding this.
Thanks,
Sai Krishna.

Hi,
Please find the application note that is availale in the link given below:
http://www.cypress.com/?rID=51581
Here in this application note, FPGA is connected to GPIF II of FX3 and data transfers are shown from FPGA --> FX3 --> PC and also in the other direction.
You can use the project files attached to that application note as starting point for your project development.
You can find the FX3 Development Kit at:
