Consider a direct mapped cache with the following characteristics 1K words 1-word blocks For this memory configuration select the correct address indexing metrics on start-up. O A. cache index: lower 10 bits cache tag: upper 20 bits Valid bit (on startup) is 0 O B. cache index: upper 10 bits cache tag: lower 20 bits Valid bit (on startup) is 0 O C. cache index: lower 10 bits cache tag: upper 20 bits Valid bit (on startup) is 1 O D. cache index: lower 12 bits cache tag: upper 20 bits Valid bit (on startup) is 1
