Optimizing Pentium Code
Chances are you've heard that the payback for optimizing code via hand-tuning for Intel's Pentium processor isn't worth the effort. That's not the case, however, as you'll see with the optimization tricks ASM-expert Mike Schmit shares here. Michael Abrash adds a few thoughts of his own. - Embedded Systems
The New New Thing
First PC apps. Then client/server. Then the Web. Now it's wireless and voice. The "New Thing" gets tacked on each time, but it's rarely integrated. So developers construct a new application from the data out to the presentation layer. Covigo wants to change that: They'd like to sell you on a single server architecture that can adapt to multiple output channels (the Web, wireless and voice) and different levels of "real-time": right now, off-line or alerts.

Pentium Optimizations and Numeric Performance
The Pentium is the first member of the Intel x86 family that requires RISC-style instruction scheduling to achieve its full potential. Steve analyzes what this means in terms of Pentium floating-point performance and how you can get full throughput from a Pentium. - Parallel
DTACK Revisited
From Hal's point of view, nothing much has happened in desktop-computing architectures since 1982. With that in mind, Hal compares the PowerPC 601 to Intel's upcoming P6.

Programming the Pentium Processor
Intel's recent entry into the 32-bit microprocessor race ups the performance ante. Our authors describe the Pentium's superscalar, pipelined architecture, focusing on floating-point code. John Dahms shares some of his experiences in writing a Pentium-aware compiler. - Embedded Systems
