Assume that propagation delay along the bus and through the ALU of Figure 15.6 are 20 and 100 ns, respectively. The time required for a register to copy data from the bus is 10 ns. What is the time that must be allowed for
a. Transferring data from one register to another?
b. Incrementing the program counter?
