9 Questions
What is the main difference between byte-addressable and word-addressable memory organizations?
Byte-addressable memory allows for accessing individual bytes, while word-addressable memory can only access full words
What are the three main addressing modes mentioned in the text?
Direct, indirect, and indexed
In a big endian system, how are the bytes of a 32-bit integer stored in memory?
The most significant byte is stored at the lowest address
What is the main advantage of little endian byte ordering over big endian?
Little endian makes it easier to place values on non-word boundaries
Suppose we have the 32-bit integer value 0xABCD1234 stored in memory. In a little endian system, how would the bytes be arranged in memory?
0x34, 0x12, 0xCD, 0xAB
Which of the following is a key advantage of big endian byte ordering?
It is more natural and intuitive for humans to understand
Suppose we have the 32-bit integer values 0xABCD1234, 0x00FE4321, and 0x10 stored sequentially in memory starting at address 0x200. In a big endian system, what would the bytes look like in memory?
0xAB, 0xCD, 0x12, 0x34, 0x00, 0xFE, 0x43, 0x21, 0x00, 0x00, 0x00, 0x10
Which of the following is a key advantage of little endian byte ordering?
It makes it easier to place values on non-word boundaries
What is the primary difference between byte-addressable and word-addressable memory in terms of memory access?
Byte-addressable memory allows access to individual bytes, while word-addressable memory can only access full words
