# This test is targeting stores
# Access pattern: A, C, E, G, A, I, A, E, K, E, G
# Each letter represents a 64-byte address range.

# The [] indicate two different sets, and each set has four ways.
# [set0way0, set0way1, set0way2, set0way3],
# [set1way0, set1way1, set1way2, set1way3],
# If you have a 512B cache with 4-way associativity,
# and each cache line is 64B.
# This test can be used to test the correctness of NRU
# replacement policy. The NRU replacement policy will always find
# the victim block from the left side of a cache. More specifically,
# with NRU replacement policy, you will observe:
# m, m, m, m, h, m, m, h, m, h, m, where 'm' means miss, and 'h' means
# hit.

# Explanation of this result:
# A, C, E, G are misses, now the cache stores ([A0, C0, E0, G0],[ , , ,]).
# The number following each letter is the NRU bit for the address range.
# A is a hit. Now the cache stores ([A0, C0, E0, G0],[ , , ,]).
# I searches a victim and selects A. Now the cache stores ([I0, C1, E1, G1],[ , , ,]).
# A searches a victim and selects C. Now the cache stores ([I0, A0, E1, G1],[ , , ,]).
# E hits. Now the cache stores ([I0, A0, E0, G1],[ , , ,]).
# K searches a victim and selects G. Now the cache stores ([I0, A0, E0, K0],[ , , ,]).
# E hits. Now the cache stores ([I0, A0, E0, K0],[ , , ,]).
# G searches a victim and selects I. Now the cache stores ([G0, A1, E1, K1],[ , , ,]).
