WebEach of the cache policy is as follows: • Write Allocation (WA) – A cache line is allocated on a write miss. This means that executing a store instruction on the processor might cause a burst read. • Write-Back (WB) – A write updates the cache only and marks the cache line as dirty. The external memory is updated only Webcache misses overall (see Figure 6). If the miss cache is increased to 4 entries, 36% percent of the conflict misses can be removed, or 18% of the data cache misses overall. After four entries the improvement from additional miss cache entries is minor, only increasing to a 25% overall reduction in data cache misses if 15 entries are provided. ninja chicken and rice recipe
