R13 off by 2 bytes. Any help? - Reverse Engineering Stack

I then padded to 8 digits and got 00FFFFFF. It doesn't. A specific address in memory generally points to one byte of memory. However, your display here is showing you every byte of memory from 0x8048384 to 0x80483A4 - That's 32 bytes of memory, organized into 2 rows of 4 4-byte values.. If you look carefully on the left side, the addresses don't increment by one between the lines, but rather by 16: 84-> 94 (in base 16), which tells you These formats include hexadecimal bytes, words (words, double words, and quad-words), integers (short, long, and quad integers and unsigned integers), floating-point numbers (10-byte, 16-byte, 32-byte, and 64-byte real numbers), and ASCII characters. The d* (Display Memory) command displays the contents of a specified memory address or range. 2018-12-12 Memory can be thought of simply as an array of bytes.

David Wentzlaff, ELE 475 – Computer Architecture. A main storage address is an index into memory. A 32-bit address is the address of a single byte. Thirty-two wires of the bus contain an address (there are many  Therefore 32 bits are required to uniquely address each 32-bit word. (b) Each word is 32 bits = 4 bytes, so if main memory is byte-addressable we have. 4 x 4  For example, a value of type int is usually 32 bits, so it occupies 4 bytes.

Se hela listan på embeddedbits.org Word-wide memory is addressed with a single address bus. When a word is read from an odd address, one byte is in one word, the other byte in another. You cannot address both bytes at the same time. Even if the memory had a separate address bus for each byte, the processor does not have the pins to address both address busses at the same time.
