I want to measure the bandwidth of the usb 2.0. I have a board with cypress Fx2 and FPGA. I have developed the firm ware in keil C.Should I code something in Keil C to measure the bandwidth delivered by USB or how can I do it ? thanks punitha
thanks
There was a program in cypress "Bandwidth meter " to the test the speed of the PC and USB. I tried it and i was able to achieve 45MB/s as peak bandwidth. But it did not involve my firmware or the FPGA. It was just to test the speed of PC. but will i get the same bandwidth when I use my firmware to transfer data? . The program in the cypress does not transfer data to th outside world.
Unless there is any packet loss, the throughput performance is the same, regardless of the place where you attach a prove, though there may be temporarily fluctuation absorbed by buffers.
Or do you want to detect packet loss?

thanks. I just want to test the performance of the USB
