AXI USB 2.0 Device: Demonstrating Performance for Bulk and Isochronous Transfers
Ravi Kiran Boddu, D.Sathish kumar · 2013
This application note demonstrates the performance measurement of the Xilinx ® universal serial bus 2.0 (USB 2.0) high-speed device with an advanced microcontroller bus architecture (AMBA®) advanced eXtensible interface (AXI) for bulk and isochronous transactions. The test system generated is based on a Kintex®-7 FPGA. The performance is measured with two separate host drivers for bulk and isochronous transactions. This application note describes how to develop a USB system and corresponding ELF files for bulk and isochronous transactions. It is assumed that the user has general knowledge of the Xilinx Platform Studio (XPS) [Ref 1].
