Modify the state diagram given in Example 7.2 for the mode of operation described in Problem 7.10 Reference of example 7.2 Example 7.2 Problem: An arbiter receives three request signals, R1, R2, R3 signals, G1, G2, G3. Request R1 has the highest priority and req An example of the operation of such an arbiter is given in Figur that describes the behavior of this arbiter Reference of problem 7.10 In the arbiter protocol example depicted in Figure 7.9, the master that receives a bus grant maintains its request line in the asserted state until it is ready to relinquish bus mastership. Assume that a common line called Busy is available, which is asserted by the master that is currently using the bus. The arbiter grants the bus only when Busy is inactive. Once a master receives a grant, it asserts Busy and drops its request, and in response the arbiter drops the grant. The master deactivates Busy when it is finished using the bus. Draw a timing diagram equivalent to Figure 7.9 for this mode of operation.
