Hi, I am having difficulty in drawing a state diagram for my homework question. Can any one of you please help me or guide me?
Thank you, I would really appreciate your help.
Question is - 1) Design an arbiter circuit to grant access to one of the three devices that may send an access request signal to the arbiter. Let the input requests to the arbiter be r1, r2, r3 the outputs will be g1, g2, g3 to grant only one of the three. Also assume priority that device 1 has higher priority than others, and device 2 has higher priority than device 3. Create a state diagram, state table and logic equations for all outputs and draw a schematic using D flip-flops. Make sure that at max only one of the three output is active at any given time.
I am confused with the inputs r1,r2,r3. Should I take two values each for r1,r2,r3 , which will be r1=0 or r1=1 . Or second scenario I have is r1r2r3 = 000 to 111, i.e., three binary numbers.
I can't understand how to solve it, please help.
