Give the following series of address references:
22,36,19,43,27,25,24,19,8,12,4,7,10,38,20,36,16
assuming a direct-mapped cache with 8 one-word blocks that is initially
empty,label each reference in the list as a hit or miss and show the final
content of the cache i)which block of cache is never used using the above
reference? ii)how many compulsory misses would occur?list them iii)how
many conflict misses would occur?
答案我貼在網路上比較清楚

我想請問各位高手
為什麼19跟36發生衝突性失誤 但是22,38的block no 一樣是6卻沒發生呢?
其他也有block no相同的也沒有發生衝突性失誤?
謝謝指教
