[5 mark] 1. Develop a mathematical model for measuring performance based on overall memory access time with a neat diagram for the following memory design and derive the formula to calculate the Overall Memory Access Time. Main Memory: Internal Cache: 1 External Cache: 1 Register S and Register B have fastest access time: Data Search order [Registers - Internal Cache - External Cache - Memory] [Hint: Register access time is considered negligible] 2. Consider the performance metrics-SPEC, QUIPS and MFLOPS. Research says these 3 metrics are 'REPEATABLE' but 'NOT RELIABLE". Give reasons for this statement. [5 mark] [5 mark] 1.
