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
