### Memory Contents and Direct-Mapped Cache Mapping #### Memory Contents The contents of the memory are as follows: | Address | Data | Address | Data | |---------|-------|---------|------| | 000 | 1000 | 100 | 0001 | | 001 | 1101 | 101 | 0011 | | 010 | 1010 | 110 | 0111 | | 011 | 1111 | 111 | 1001 | #### Cache Mapping Instructions By using direct-mapped cache, please map the following addresses from main memory to the cache in the order: 001, 010, 100, 101, 111. ### Explanation: 1. **Address Mapping:** - **001:** The address 001 in the main memory has the data 1101. - **010:** The address 010 in the main memory has the data 1010. - **100:** The address 100 in the main memory has the data 0001. - **101:** The address 101 in the main memory has the data 0011. - **111:** The address 111 in the main memory has the data 1001. Each address and its corresponding data are placed into the cache based on the direct-mapped cache policy, which maps each block of main memory to exactly one cache line. ### Note: Direct-mapped cache is a simple form of cache organization where each block of main memory is mapped to exactly one cache line. This mapping is typically achieved using a modulo operation.
