Q46

Consider a system with $1$ MB physical memory and a word length of $1$ byte. The system uses a direct mapped cache, with block numbers starting from $0$. The word with physical address $\text{0xA2C28}$ is mapped to the cache block number $176_{10}$. The maximum possible size of the cache (in KB ) for this configuration is $\_\_\_\_\_\_\_$. (answer in integer) Note: $1 \mathrm{~K}=2^{10}$ and $1 \mathrm{M}=2^{20}$
