sending 64 bit from fpga to hs to terminal in pc @10k

hi, 

i had a terasic sockit (which had a cyclone 5 soc). i already implemented sending 64 bit data from fpga to pc by using nios2 processor  

( nios2+jtag uart_onchipram). but its speeed is very low(around 2to 3khz) , i am not able to get 10khz speed. so what should i do?? 

 

sockit had a usb to uart port which is integrated to hps, i think by using it, i can increase the speed. but how can i use it? 

along with hps what are the components i need to use in QSYS system? 

if anybody got a reference program lease share the link , it will be very helpful to me :) 

 

is it possible to use qsys system to run the hps like i did using nios2 processor ?( is it possible to use hps without booting form an sd card) 

if it not possible how can i do it , any tutorial for that ? 

 

my future work is to change one register value inside fpga from a terminal form pc (using hps) . 

 

if anybody know any information regrading this, please share ( i am using quartus 16.0 lite edition in windows7) 

 

 

thanks and regards

Hi dipin555, 

 

You can obtain many useful information on booting Linux using HPS at rocketboards.org. 

For example, here are instructions on booting Linux using precompiled binaries on SD Card on the Arrow SoC kit (same as Terasic Cyclone V SoC kit):
