The formula to calculate the Hit Ratio is:
\[ HITR = \frac{H}{H + M} \times 100 \]
Where:
Let's say there are 80 cache hits and 20 cache misses. The hit ratio would be calculated as follows:
\[ HITR = \frac{80}{80 + 20} \times 100 = 80\% \]
So, the hit ratio is 80%.
The hit ratio is a percentage that represents the proportion of cache hits relative to the total number of cache accesses (hits plus misses). It is calculated by dividing the number of hits by the sum of the number of hits and misses, then multiplying by 100. This metric is often used in computing to assess the efficiency of cache memory.
