| Case Study: “Your Mileage May Vary:” Creating Reliable Comparisons of IP Cores |
By BDTI, 8/20/2008
An attractive attribute of licensable processor cores is the flexibility chip designers have to adapt these cores to their chosen fabrication process, cell library, tool flow, logic synthesis goals and other conditions. In other words, chip designers can tune the core to the needs of a particular application and to their preferred chip design methodology. An unfortunate side effect of this flexibility is that it can be extremely difficult to make apples-to-apples comparisons between licensable cores.

| Jeff Bier's Impulse Response—Risky Business |
By Jeff Bier, 6/18/2008
If you were getting ready to buy a new high-end camcorder or a new car, chances are you’d spend some time reading independent reviews. Maybe you’d pick up a copy of Consumer Reports or Road and Track. Perhaps you’d scan Amazon.com for user evaluations. Whatever. The point is, you probably wouldn’t just make your choice based on the vendor’s marketing claims, right?

| Case Study: Change or Be Changed: Good Business Decisions Require Good Information |
By BDTI, 2/27/2008
The electronics industry has long been a dynamic one, but never as dynamic as it is today. Private equity investors now own some of the largest semiconductor companies and are pushing for improved efficiencies. Many, if not most, of the largest chip companies are making significant adjustments in their strategies. And, as usual, changes in technology—often driven by innovative start-ups—threaten to disrupt the status quo.

| Case Study—BDTI Benchmarks Help Vendors Win New Customers |
By BDTI, 12/19/2007
Smaller fabless chip vendors face an uphill battle: to beat out larger rivals, they must attract the attention of potential customers, prove the advantages of their products, and demonstrate that they will be reliable, long-term partners. One such company recently used BDTI Benchmarks to accomplish all three of these objectives.

| Evaluating the DSP Capabilities of the Cortex-R4 |
By BDTI, 12/6/2007
In 2004, ARM announced its newest generation of licensable cores, called the “Cortex” family. Cortex cores span a wide range of performance levels, with Cortex M-series cores at the low end, Cortex R-series cores providing mid-range performance, and the Cortex A-series applications processors offering the highest performance. The first Cortex core to be announced was the Cortex-M3, and since then ARM has announced several others, including the Cortex-A8 and A9, the Cortex-M1, and the Cortex-R4.

| Case Study: Custom Benchmark Analysis—Making the Numbers Work For You |
By BDTI, 7/18/2007
Processor designers, marketers, and users with a sophisticated understanding of benchmarks know that raw benchmark results rarely give the most accurate picture of processor performance for a specific application scenario. While useful for providing a general impression of processor capabilities, raw benchmark results must be adapted to give a clear sense of how processors will perform in a particular application.
