The intrinsic switching delay of semiconductor devices (t = CV/I) has improved steadily at a rate of around 20 percent per year, due mostly to device scaling. Global interconnect delays have scaled less favorably, limiting overall chip gains to somewhat less. Over the next several years, the ITRS 2001 calls for intrinsic switching delays to improve at about 17 percent per year. Local interconnect performance will scale similarly, but global interconnects will lag, requiring circuit design tricks to keep pace.

There has long been talk of finding applications that will push the PDA or smart phone beyond the interests of the geek or professional to the mass market, and WLAN could be the energizing factor. According to In-Stat/MDR, revenue from WLAN chipsets will nearly double from 2002 to 2003, but some remain skeptical of its ability to catch the public's imagination.

Rassweiler noted that other EMS providers, such as Sanmina-SCI Corp., San Jose, and Viasystems Inc., St. Louis, have also lost money on their PCB operations, despite being a one-stop source of boards and EMS services.

Next month should be key, as September always is. The supply channel is clearly starting to prepare for the Christmas cycle, which starts soon. This run is particularly critical for the quarter and it will be key to next year,” it added.

SIMD speedup does not have to be taken in the form of performance. It could be taken as a power savings. Let's say we were to add SIMD to a processor and get some degree of application-level speedup. This gain could instead be used to reduce operating frequency while holding performance constant. The SIMD units add transistors, but dynamic power consumption goes up only linearly with transistors. Lowering frequency, on the other hand, not only lowers the power directly, but it also allows the supply voltage to be lowered, which is a quadratic term in the power equation (P=CV2 F).

Furthermore, while the SIMD units may add transistors, they may not add silicon area. A lower operating frequency would allow the core to be optimized for area rather than speed. The difference can be significant; indeed, die size might actually be lower with the SIMD units than without.

TI knows all the pros and cons and has effectively shrugged them off. By combining TI's advanced process technology and our complete systems understanding,” Engibous said, we will enable our customers to deliver wireless phones and PDAs with voice, data and multimedia without increasing size and power consumption.”

We were able to raise money by selling intellectual property, and we formed DSP Architectures at the end of 1996,” Fleming said.

As previously pointed out, one limitation on ILP hardware is the lack of parallelism in a single instruction stream. Another impediment is the presence of long-latency operations, such as memory accesses. Both problems stall the instruction pipeline, reducing the average instruction issue rate and leading to under utilization of the execution units.
