If you want an image of how large it is, first imagine the maximum 4,294,967,296 bytes in a 32-bit address space. Now imagine 4,294,967,296 32-bit address spaces; that's one 64-bit address space.

Porting legacy code from 32-bit to 64-bit requires knowledge of the data types and the C and C++ rules that govern ILP32 and LP64. Using quality tools can help developers find and fix defects quickly ...

Enhanced 64-bit support led off Apple's preview of OS X 10.5. But it's a feature that will likely matter only to developers who create data-intensive applications.

Dates and times stored in 32 bits on Unix-like systems will “overflow” in early 2038 — but the problems, and the patches, ...

For starters, the ISA makes all processing 64-bit native, operating on 64-bit data inside the processor's execution units. There's no special processing mode to use 64-bit data types, or ...

Here’s the real difference between 32-bit and 64-bit. Here’s why it matters Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data at once.

The 64-bit instruction set is a proper superset of the 32-bit version so there is no mode switch necessary. The additional instructions support 64-bit data types along longer relative referencing.

AMD's Hammer features a 64-bit mode with a 64-bit address space and a 64-bit data space. The processors will be able to detect whether a 64-bit or 32-bit mode is required at any time.

Thought Windows on ARM was snazzy? Have a gander at this. The outfit's forthcoming ARMv8 architecture, the first ARM architecture to include a 64-bit instruction set, has just been detailed, with ...

SAN FRANCISCO (CBS.MW) -- Intel said Tuesday it plans to bring 64-bit data crunching power to its low-end server chips in a plan that follows the path of rival AMD. Intel INTC, -3.30% shares rose ...
