It was otherwise identical to the 1984 design, except for two 64-kilobit × 4-bit DRAM chips which replaced the original eight 64-kilobit × 1-bit ICs. After the release of the Commodore 64C, MOS Technology began to reconfigure the original C64's chipset to use HMOS technology. The main benefit of HMOS was that it required less voltage to drive ...
In cryptography, the Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code.It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop.

A 64-bit word can be expressed as a sequence of 16 hexadecimal digits. In computer architecture, 64-bit integers, memory addresses, or other data units [a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of ...
Vector processor. In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data called vectors. This is in contrast to scalar processors, whose instructions operate on ...
The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new ...
The updated instruction set is grouped according to architecture (i186, i286, i386, i486, i586/i686) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64). Original 8086/8088 instructions. This is the original instruction set. In the 'Notes' column, r means register, m means memory address and imm means immediate (i.e. a ...
