In computing, octuple precision is a binary floating-point-based computer number format that occupies 32 bytes (256 bits) in computer memory. This 256-bit octuple precision is for applications requiring results in higher than quadruple precision. The range greatly exceeds what is needed to describe all known physical limitations within the ...
The goal of loop unwinding is to increase a program's speed by reducing or eliminating instructions that control the loop, such as pointer arithmetic and "end of loop" tests on each iteration; [2] reducing branch penalties; as well as hiding latencies, including the delay in reading data from memory.

SHA-256 hash function. Smart contracts use 256- or 257-bit integers; 256-bit words for the Ethereum Virtual Machine. "We realize that a 257 bits byte is quite unusual, but for smart contracts it is ok to have at least 256 bits numbers. The leading VM for smart contracts, Ethereum VM, introduced this practice and other blockchain VMs followed." [8]
1,024 bits (128 bytes) - RAM capacity of the Atari 2600: 1,288 bits (161 bytes) – approximate maximum capacity of a standard magnetic stripe card: 2 11: 2,048 bits (256 bytes) – RAM capacity of the stock Altair 8800: 2 12: 4,096 bits (512 bytes) – typical sector size, and minimum space allocation unit on computer storage volumes, with ...
Rust features crafting, though initially limited until the discovery of specific items in the game's open world. To stay protected, players must build bases or join clans to improve their chance of survival. Raiding is a major aspect of Rust. Rust supports modded servers which can add additional content.
A processor with 128-bit byte addressing could directly address up to 2 128 (over 3.40 × 10 38) bytes, which would greatly exceed the total data captured, created, or replicated on Earth as of 2018, which has been estimated to be around 33 zettabytes (over 2 74 bytes). [1] A 128-bit register can store 2 128 (over 3.40 × 10 38) different values.
In 8-bit CP/M versions it is located in the first 256 bytes of memory, hence its name. The equivalent structure in DOS is the Program Segment Prefix (PSP), a 256-byte (page-sized) structure, which is by default located exactly before offset 0 of the program's load segment, rather than in segment 0.
In order to make up somewhat for the lack of registers, the 6502 includes a zero page addressing mode that uses one address byte in the instruction instead of the two needed to address the full 64 KB of memory. This provides fast access to the first 256 bytes of RAM by using shorter instructions. For instance, an instruction to add a value from ...
