b. A microprocessor has an instruction set that consists of 117 instructions, which need fetch, decode, read operand, execute, write and interrupt stages. Assume that as an average, each stage requires three micro- operations to complete. Also, assume that the control memory is N bits wide (i.e., control field bits + address selection field bits + address-one bits + address-two bits N bits). The control field bits are 15 and there are 15 flags to be monitored. i. How many...

Assume that forwarding is not implemented and only the hazard
detection and stall logic is
implemented so that all data dependencies are handled by having the
pipeline stall until the
register fetch will result in the correct data being fetched.

The Fibonacci sequence F is defined as F(1) = F(2) = 1 and for n>= 2, F(n + 1) = F(n) + F(n − 1) i.e., the (n + 1)th value is given by the sum of the nth value and the (n − 1)th value. 1.
