The EDUC-8 was an 8-bit bit-serial design with 256 bytes of RAM. The internal clock speed was 500 kHz, with an instruction speed of approximately 10 kHz, due to the bit-serial implementation. The instruction set was a subset of the DEC PDP-8, though it was missing quite a few of the PDP-8’s instructions and some important flags. This was ...
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]
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 unit allocated itself the top 256 bytes of memory at switch-on and moved down the USR graphics and RAMTOP. This made it incompatible with some programs, particularly games, which use that space for machine code. For cost reasons, the unit did not provide for daisy-chaining of further devices on the computer's expansion port.
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 ...
The need to move more than 256 bytes within main memory had historically been addressed with software [33] (MVC loops), MVCL, [34] which was introduced with the 1970 announcement of the System/370, and MVPG, patented [35] and announced by IBM in 1989, each have advantages.
The zero-page, the first 256 bytes of memory that were used as pseudo-registers, could now be moved to any page in main memory using the B(ase page) register. The stack register was widened from 8 to 16-bits using a similar page register, SPH (stack pointer high), allowing the stack to be moved out of page one and to grow to larger sizes.
Default VGA 256-color palette. Mode 13h is the standard 256-color mode on VGA graphics hardware introduced in 1987 with the IBM PS/2. It has a resolution of 320 × 200 pixels. [1] It was used in computer games and art/animation software of the late 1980s and early to mid-1990s. [citation needed] "13h" refers to the number of the mode in the VGA ...
