| Cradle's Lineup Gets Major Upgrade |
By BDTI, 4/11/2005
Last month Cradle introduced the CT3600 family, the successor to its original CT3400 chip. The CT3600 family—which includes the CT3608, CT3612, and CT3616—will
offer major improvements over the CT3400 in the areas of parallelism,
clock rates, and on-chip integration. Like the CT3400, the CT3600
family will primarily target digital video applications, particularly
multi-channel surveillance applications.

| Freescale Fills its DSP Ranks |
By BDTI, 4/11/2005
Last month Freescale added two new parts to its MSC711x family of
StarCore SC1400-based DSPs. The new parts will operate at 300
MHz--50% faster than the existing 200 MHz parts. Both new chips
will also feature 472 Kbytes of on-chip memory, up from a maximum of
408 Kbytes on existing chips. Not surprisingly, the new chips are
also more expensive: the MSC7118 and MSC7119 will cost $33 and $35,
respectively, up from a maximum of $25 for the existing family members.

| Measuring Multimedia Performance |
By BDTI, 4/11/2005
At first glance, measuring processor performance on multimedia
applications can seem straightforward. Many multimedia applications are
based on published standards and widely available software. Hence,
measuring multimedia performance may seem to be a simple matter of
checking published performance data. In reality, however, reliable
measures of processors’ multimedia performance are hard to obtain.

| Jeff Bier's Impulse Response – Optimization: It's Not Just for Compilers |
By Jeff Bier, 4/11/2005
Many of the new processor announcements I’ve seen recently stress “compiler friendliness” as one of the main advantages of the new architecture. And vendors like to boast about the enormous amounts of time and money they’ve spent improving their compilers. For engineering managers with tight budgets, it is tempting to buy into the idea that creating efficient code requires nothing more than setting the appropriate compiler options. Unfortunately, this is rarely the case.
