Daffodil International University Faculty of Science & Information Technology Department of Software Engineering Course Code: SE222, Course Title: Computer Architecture Quiz-1 (Fall 2026) Section: 46 L Marks: 15 Student ID : 1. A program executes the following instruction mix on a 2 processor - Instruction Type | CPI | Instruction Mix Integer arithmetic | 3 | 30% Load | 4 | 40% Store | 5 | 10% Branch | 1 | 20% a) Compute the average CPI of the processor using the given instruction mix. (3 marks) b) If the program has 20,000 store instructions, compute the instruction count and MIPS of the program, if the execution time is 200ns. (3 marks) 2. Rahim and Tanvir designed processors with different transistor growth rates. Rahim’s processor doubles its transistor count every 2 years, while Tanvir’s processor doubles its transistor count every 3 years. In 2026, Rahim’s processor has 500 million transistors, while Tanvir’s processor has 1,000 million transistors. Estimate the year in which their predicted transistor counts become equal and determine the transistor count of each processor in that year. (5 marks) 3. Explain the four major steps involved in the execution of an instruction in a processor. (4 marks)
