Is the time right to move from RISC to Intel Architecture?

Previous business decisions to deploy your IT solutions on RISC based architectures was most likely the right decision at the time based on the business need, the solutions availability and the architecture available to run that solution. Some of these solutions are likely due for an upgrade due to...

Migrating From UNIX/RISC to Red Hat Enterprise Linux on Intel Processor-Based Servers: Driving Higher Value Deep Into the Data Center

Red Hat Enterprise Linux running on Intel processor-based servers is helping companies cut TCO by up to 50 percent and more versus comparable UNIX/RISC solutions, while providing a better foundation for growth. This white paper outlines the key benefits of migration and provides a step-by-step guide to planning and conducting...

Staff Cost Savings Models to Justify RISC Migration

In the past, RISC-based servers delivered performance and memory advantages that made them the workhorses of corporate computing. And even though the systems used expensive, proprietary components and were expensive to operate, many organizations ran their critical business applications - including database, ERP, CRM, DNS server, and others - on...

The XO-2 is going Embedded RISC? So will everyone else!

Yesterday,  OLPC project founder Nicholas Negroponte indicated that their next generation XO-2 will almost certainly eschew it's current x86-based design and move towards one that is based on the ARM, the most common embedded RISC architecture in the world. It's used in over a billion cell...

When Good Instructions Go Bad: Generalizing Return-Oriented Programming to RISC

This paper reconsiders the threat posed by Shacham's "Return-oriented programming" - a technique by which OX-style hardware protections are evaded via carefully crafted stack frames that divert control flow into the middle of existing variable-length x86 instructions - creating short new instructions streams that then return. The paper believes this...
