<p>The so-called ‘Cell Reference Set’ development platform will incorporate a Cell processor, peripheral chips mounted on a PCB with a general-use interface, peripheral equipment such as DVD and HDD drives, and cooling equipment.</p>

Der häufigste Fehler in dieser Phase des Projekts besteht darin, dass keine umfassende Verifikationsdiskussion mit allen Beteiligten stattfindet. Die Festlegung und Dokumentation der Verifikationsziele ist die einzige Möglichkeit um zu erkennen, ob die Spezifikationen voll erfasst und verstanden werden.

The MT9P001, a 1/2.5-inch optical format CMOS sensor, which can be used for DSCs, camera phones and PDAs, shoots 12 frames per second (fps) at full resolution (2,592 H x 1,944 V), enabling high-speed performance, and up to 30 fps in preview mode. It also incorporates an on-chip, 12-bit analog-to-digital converter (ADC), which enables high-resolution image capture that matches that of CCD-based DSCs.

The 1/2.5-inch optical format matches the CCD and enables a very small footprint module for the camera phone market, said Klein, and the 12-bit ADC enables high resolution.

Other MT9P001 features include global reset release (reduces distortion when used with a mechanical shutter), electronic rolling shutter, flash support, 60 dB dynamic range and fail safe I/O (reduces standby power). Programmable controls are available for gain, frame rate, exposure time, horizontal/vertical blanking, and left-right/top-bottom image reversal. These devices are available in die form or in a 48-pin imaging LCC (iLCC) package.

Most of these cameras use a rolling shutter mode, which is an engineering tradeoff because it will produce [image] artifacts. Engineers have decided to live with it because of cost and performance reasons,” Klein said.

However, if you have a fast frame rate you can actually get pretty good results with a rolling shutter. Folks have typically limited the frame rate to 15 fps when deciding to use or not use a mechanical shutter,” he said.

The good news is with the new global reset capability, it simplifies and reduces the cost of adding a mechanical shutter by allowing for an electronic reset of the entire array at one time which is equivalent to opening a mechanical shutter,” Klein said.

Targeting camera phones and PDAs, the MT9T012, a 1/3.2-inch optical format CMOS sensor, shoots at 15 fps at full resolution (2,056 H x 1,544 V) and up to 30 fps in preview mode. The 1/3.2-in. optical format and 2.2 micron pixel is very important to have to achieve a small size and this kind of optical format will allow for a 9.5 x 9.5-mm module, Klein said.

In the short term, Feldhan is bullish for this year and next. We’re upbeat,” he said in an interview at the Semico Outlook Conference on Thursday (September 15).

We’re not going to mimic what everyone else says,” he said. We still see a lot of innovations.”

Feldhan was referring to the growing number of pessimistic forecasts from other, undisclosed research houses. Gartner, iSuppli and others have published relatively bearish forecasts for semiconductors.

A rapid rise in energy prices coupled with a growing excess of manufacturing capacity has recently prompted iSuppli Corp. to trim its semiconductor industry forecast for 2005.

iSuppli (El Segundo, Calif.) now projects global semiconductor sales to reach $232.7 billion in 2005, up 2.4 percent from $227.2 billion in 2004. For 2006, sales are projected to rise 4.3 percent to $242.8 billion. The firm previously projected a 5.9 percent sales increase in 2005, followed by a 3.9 percent increase in 2006 (see Sept. 8 story).

Samples of the XRT86SH328 are available in 30 days. In 1,000-piece quantities, the device costs $151 each. It is available in a PBGA package.
