how to using USB (CY7C68013) with Cyclone III

Hi, I have 2 questions regarding Cypress CY7C68013A with Cyclone III. Which SLS usb ip is the right one? Does it allow USB to get connected to Avalon Bus? Thanks, gl888

Once again, many thanks for the information.

Another question, given the USB is used at high data throughput,

how much involvement from embedded processor (not the one in USB chip,

but the NiosII in FPGA) is needed in both cases?

1. using ISP1504/usb3300

2. using cy7c68013a

Does the processor need to response to interrupt at the end of each frame

to set up data transfer ?

Thanks,
