For the following question, examine the following code: 1 ADD X1, X2, X3 2 SUB X2, X1, X5 3 LDUR X8, X5, 0] 4 ADD X7, X8, X6 Assuming hardware hazard detection and no forwarding hardware, what is the CPI of this code (you may assume that this is in the middle of a long string of instructions so initial pipeline fill time is 0)

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
