QED may lose spot in GI's set-top
By Junko Yoshida
HORSHAM, PA. — Reversing a statement made public in March, General Instrument Corp. has acknowledged that Quantum Effect Design Inc. (QED), a high-speed, high-performance MIPS RISC design house based in Santa Clara, Calif., may be losing out on a huge design win for a key CPU in millions of GI's advanced interactive digital cable set-top boxes.
The possible switch on the CPU supplier for GI's digital set-top suggests continuing behind-the-scenes wrangling for design wins among major component suppliers, while the leading cable set-top vendor struggles to shave every penny off its new system in order to keep the interest of cable operators.
GI claims that 12 leading North American cable-system operators have already ordered 15 million of its digital cable boxes, making the design win for this key CPU an important one for the eventual winner.
"We are committed to the MIPS-based CPU architecture," said Denton Kanouff, GI's vice president of marketing for digital network systems. "Because there are multiple MIPS RISC CPU suppliers out there, we don't have to get locked in with any one particular vendor until we place the final order in the fourth quarter of this year."
Kanouff's statement, however, contradicts GI's own announcement made on March 25, in which it listed QED's component as "the microprocessor of choice" for the company's upcoming DCT-5000 advanced digital interactive cable set-top.
Kanouff confirmed this week that GI is currently evaluating "NEC, QED and a few other MIPS CPU vendors" as the possible key supplier for the first production version of the DCT-5000. "This is a very competitive business. Nothing has been decided yet," he said. "We're conducting ongoing evaluations over features, pricing and availability among different vendors' MIPS products."
An industry source close to GI's set-top designs, speaking on the condition of anonymity, noted that, to QED's loss, NEC recently won the battle for GI's DCT-5000 set-top box. Although Kanouff declined to confirm that NEC is now the vendor of choice, GI has apparently begun distancing itself from QED, and is no longer calling the Santa Clara-based company its chosen CPU partner.
Meanwhile, QED would neither deny nor confirm the latest development. Rick Kepple, vice president of marketing at QED, said that the only public statement that's available today regarding QED's involvement in the DTC-5000 set-top is GI's March press announcement. Asked if their relationship with GI has changed since then, Keppler said, "that's a private discussion between the two companies. There is nothing we can publicly disclose today."
In a previous interview with EE Times in March, Kepple said that QED's RM5230, to be designed into GI's DCT-5000, is a 64-bit MIPS microprocessor with a 32-bit system bus interface, made to provide workstation-class performance at an affordable price for consumer applications. It will offer "soft modem functionality and voice-over-telephony technology, in addition to a wide range of graphics capability," Kepple said.
According to GI's Kanouff, the set-top vendor is looking for a MIPS CPU with a processing power that matches or exceeds that of QED's proposed MIPS microprocessor. QED's MIPS RM5230 is a 233-MIPS processor running at 175 MHz. The DCT-5000's CPU must be able to run real-time operating systems, and be capable of handling simultaneous real-time interactive streams such as IP telephony and Web browsing, in addition to digital cable broadcast, Kanouff said. "Technologies are changing so fast these days. We are looking for a pretty powerful, high-speed MIPS CPU, which has more Mips power left free for processing for a variety of software applications."
Meanwhile, NEC declined to comment on the GI design-win issue. An NEC spokeswoman said, "We can't either confirm or deny it, until we make a public announcement."
Neither QED nor GI would say whether cost had become the major factor, prompting GI to start looking around for other MIPS CPU options, such as NEC's.
Previously, however QED's Kepple claimed that through manufacturing agreements with Taiwan Semiconductor Manufacturing Co. and IBM, QED has made a successful transition from design house to a fully established fabless semiconductor company. QED now has the capability to turn around high-performance MIPs processors for the consumer market that are still very cost-effective, he said.
Kaunouff predicted that GI is most likely to announce the company's final decision on a CPU vendor for the DCT-5000 just before the Western Cable Show scheduled in December. The company already has a DCT-5000 development platform up and running and available for software developers, but it will not have the first production version of the DCT-5000 box until the beginning of 1999. GI will start shipping the DCT-5000 in the second quarter of 1999.
Other major chips that go inside the DCT-5000 box include a single-chip MPEG-2/Dolby digital decoder IC designed by GI and Broadcom; a derivative of ATI Technologies' Rage PRO 2D/3D/Video graphics accelerator; and Broadcom's most recently announced single-chip DOCSIS version 1.0-compliant cable modem solution, called BCM3300.
Some of the 15 million units of digital cable boxes GI claims to have received a commitment for will be DCT-1000s and DCT-2000s. These are much simpler video-on-demand digital set-tops that do not include a cable modem or the IP telephony capabilities required by the DCT-5000. "The mix of DCT-1000, -2000 and -5000 [boxes] has to be determined by each cable operator. We don't know what the breakdown is going to be at this point," said Kanouff.
Meanwhile, GI plans to add new versions of the DCT-5000 over the year. One of them will be a version capable of HDTV decoding, slated for launch towards the end of 1999, said Kanouff. |
