Se hela listan på cs.ecu.edu An Address Refers to a Byte of Memory Conceptually, memory is a single, large array of bytes, each with a unique address (index) Each address is just a number represented in fixed-length binary Programs refer to bytes in memory by their addresses Domain of possible addresses = address space 2K byte memory or 4K X 8 , 4K byte memory which contains 4096 locations, where each location contains 8-bit data. Only one f the 4096 locations can be selected at a time. In general, to address a memory location out of 'N' memory locations, one would require at least 'n’bits of address i.e. 'n' address lines where Byte Ordering. The bytes within a multi-byte data item can be numbered from Left-to-Right (Big-Endian) or from Right-to-Left (Little-Endian).

number of physical memory connectors or amount of soldered-on memory). Byte addressing means memory is organized and accessed as a sequence of bytes. Whether one or more bytes are being accessed, a byte address is used to locate the byte or bytes memory. The range of memory that can be addressed is called an address space. Byte-addressable where each address identifies a single byte of storage.

there is an address x which points to that specific byte. Since there are 2^32 different numbers you can put into a 32-bit address, we can address up to 2^32 bytes, or 4 GB. It sounds like the key misconception is the meaning of "byte addressing." When byte processing is to be a significant part of the workload, it is usually more advantageous to use the byte, rather than the word, as the unit of address resolution.

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.

Address values which differ by one designate adjacent bytes in memory. This allows an arbitrary character within a character string to be addressed straightforwardly. In theory, modern byte-addressable 64-bit computers can address 2 64 bytes (16 exbibytes), but in practice the amount of memory is limited by the CPU, the memory controller, or the printed circuit board design (e.g. number of physical memory connectors or amount of soldered-on memory). Byte addressing means memory is organized and accessed as a sequence of bytes. Whether one or more bytes are being accessed, a byte address is used to locate the byte or bytes memory.

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. It doesn't store only one byte; it stores an entire word (the size of the processor's database). If you're talking about how the size is computed, that is done to standardize the product offerings of different vendors.
