1. Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses: 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 [6 pts] a. For each of these references, identify the binary address, the tag, and the index given a directmapped cache with 16 one-word blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. Show all your work.

It is paramount to notice that since we have word blocks and no address is separated then there are zero cache hits.Therefore the address sequence exhibits no temporal locality.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
