Suppose we have an 8 block cache. Each block of the cache is one word wide. When a given program is executed, the processor reads data from the decimal addresses show below. 4, 7, 10, 11, 4, 8, 12, 7 Show the contents of the cache at the end of the above reading operations if the cache is 4-way set associative. Assume blocks will be filled starting at block position zero and the replacement policy is LRU. Use 4 or [ 4 ] to represent the contents of memory at address 4. If the block is empty, enter [ empty ]. Set # Block Position Contents of Data Cache 0 0 1 2 3 1 0 1 2 3

The set for block position contents of data cache 0 0 1 2 3 1 0 1 2 3 is as follows:

Explanation:

Total number of blocks = 8

The cache mapping used is 4 way set associative.

Number of sets = 8 by 4 = 2 that is set 0 and set 1.

The mapping in a set associative takes place as:

Location for a memory block in cache = Memory block mod number of sets in the cache.

The first address is 4.

Location of the block with address 4 = 4 mod 2 = Set 0.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
