64-Bit

Editor's Note | News | Features | 64-Bit RSS Feed

Big words, many cores, fast clocks ı Best tools and best practice for squeezing best ROI from next-gen platforms, and development efforts.


Editor's Note

This issue, Dr. Dobbıs Ed Nisley runs down the current flock of schema for on-chip and Flash serial memory, and discusses techniques and standards evolving to permit code in such memory to XIP (eXecute In Place). He extends his discussion to address the question of whether or not code execution within the stack is possible in todayıs latest 64-bit designs (uhhh ı yes), talks about hacks and methods for defending against them that go beyond the chipıs native no-execute permissions. Meanwhile, if scaleıs your thing, Brad Martin, Anita Rettinger, and Jasmit Singh of Visual Numerics describe the process they invented for managing an elephantine migration of a 300,000-line, 32-bit app (on 11 platforms!) to 64 bits (hint: stay organized).
