QBNE (Quick branch not equal)
Using the PRU in the Beaglebone black (AM335x 1GHz ARM® Cortex-A8) I am asking how many cycles requires the instruction QBNE?
qbeq myLabel, r1, 0
I suppose two if the comparison is false: one is for compare and one is for the jump.
Instead, one, just the compare.
Thanks,
Br
Hi suomi,
Isn't it that if the comparison is false there should be no jump?

if (r1 != 0 ) jump
Anyway, how many cycles does it require?
The PRU isn't an ARM core - it's a TI developed custom RISC microcontroller. You may get more answers asking on the TI developer forums.
HTH, Pete
