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 ...
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 ...
AMD Athlon (early version), a technically different but fully compatible x86 implementation. x86 (also known as 80x86[ 3] or the 8086 family[ 4]) is a family of complex instruction set computer (CISC) instruction set architectures [ a] initially developed by Intel based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU).
Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point . Double precision may be chosen when the range or precision of single precision would be insufficient.
Processor (computing) In computing and computer science, a processor or processing unit is an electrical component ( digital circuit) that performs operations on an external data source, usually memory or some other data stream. [ 1] It typically takes the form of a microprocessor, which can be implemented on a single or a few tightly ...
Intel Core. Max. CPU clock rate. Intel Core is a line of multi-core (with the exception of Core Solo and Core 2 Solo) central processing units (CPUs) for midrange, embedded, workstation, high-end and enthusiast computer markets marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time ...
For the linguistics term "question word", see Interrogative word. In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits [ a ] in a word (the word size, word width, or word length ...
