Alternatively many word-oriented machines implement byte operations with instructions using special byte pointers in registers or memory. For example, the PDP-10 byte pointer contained the size of the byte in bits (allowing different-sized bytes to be accessed), the bit position of the byte within the word, and the word address of the data ...
wc (short for word count) is a command in Unix, Plan 9, Inferno, and Unix-like operating systems.The program reads either standard input or a list of computer files and generates one or more of the following statistics: newline count, word count, and byte count.
Because the Alpha uses byte addressing, this offset is still represented in the least significant bits of the address (rather than separately as a wide address), and the Alpha conveniently provides load and store unaligned instructions (ldq_u and stq_u) which ignore those bits and simply load and store the containing aligned word. [2] The later ...
The byte, 8 bits, 2 nibbles, is possibly the most commonly known and used base unit to describe data size. The word is a size that varies by and has a special importance for a particular hardware context. On modern hardware, a word is typically 2, 4 or 8 bytes, but the size varies dramatically on older hardware.
Move 64 bytes as Direct Store. MOVDIR64B reg,m512: 66 0F 38 F8 /r: Move 64 bytes of data from m512 to address given by ES:reg. The 64-byte write is done atomically with Direct Store. [ai] 3 Tiger Lake, Tremont, Zen 5: WBNOINVD Whole Cache Writeback without invalidate. WBNOINVD: F3 0F 09: Write back all dirty cache lines to memory without ...
In all cases the source register contains the address of the first word or byte of memory to be moved, and the destination register contains the address of the first word or byte of memory to receive the data being moved. The number of words or bytes being moved is contained in R0 as a unsigned integer. The count ranges from 1–65536.
Gulliver's Travels by Jonathan Swift, the novel from which the term was coined. In computing, endianness is the order in which bytes within a word of digital data are transmitted over a data communication medium or addressed (by rising addresses) in computer memory, counting only byte significance compared to earliness.
Very often, when referring to the word size of a modern computer, one is also describing the size of address space on that computer. For instance, a computer said to be "32-bit" also usually allows 32-bit memory addresses; a byte-addressable 32-bit computer can address 2 32 = 4,294,967,296 bytes of memory, or 4 gibibytes (GiB). This allows one ...
