On Thursday, Intel Corp. announced it would acquire DSP Communications for $1.6 billion in cash as part of a move to expand its position digital signal processing applications for cellular phone systems and Internet communications (see Oct. 14 story).

However, the companies will not co-develop products, nor will their product development paths cross. In fact, the manufacturing processes each company will come away with as a result of the research will look considerably different, said Ronnie Vashista, LSI's director of ASIC marketing.

We will co-develop specific process modules, but in the end, the process flows will look very different because we will tailor them to our own individual products, which, for LSI, tend to be more on the custom side,” Vashista said.

Research teams of 50 to 100 employees from both companies have been engaged for several weeks in a number of activities, company officials said. The first fruit of the alliance will be LSI's eDRAM ASICs, based on Hitachi's 0.20-micron, 1.8-V embedded-DRAM process and LSI's CoreWare IP and design libraries. In qualification stages now, the process is expected to reach production by mid-2000.

Previously, LSI worked with Micron Technology Inc. to evaluate the potential of embedded DRAM, but the partnership dissolved a few years ago when the companies' product paths took different turns.

We decided that, initially, we wanted to have a foundry relationship, and one that is sensitive to the requirements of the system-on-a-chip industry,” Vashista said. It so happens that Hitachi has a mature and viable technology in-house already, which we don't have. We will add value in the IP we port to the technology, as well as the design environment around it.”

The foundry aspect of the relationship is expected to remain limited to embedded DRAM products, although the possibility of LSI licensing Hitachi's process for use in its own fabs is still open, he added.

The deal bolsters LSI's recently announced initiative to expand its manufacturing base by outsourcing as much as 25% of its production. Most recently, LSI licensed its process technology to Malaysian foundry start-up Silterra (Malaysia) Sdn. Bhd. in exchange for future capacity and a small stake in the fab.

In the area of process development, the partnership will draw on each company's strengths to address the complexities of deep-submicron designs-for example, Hitachi's and LSI's copper interconnects both work with low-k dielectric materials, said Masahiko Ogirima, Hitachi's senior vice president of semiconductors and ICs, Tokyo.

Both Hitachi and LSI Logic will be able to increase their market leadership by combining their technology strengths,” he said.

This is not a time for Sun and Fujitsu to compete,” he said. We have to work together to make [software] development more efficient.”

Currently, Fujitsu and Sun use a common hardware/software interface for the Sparc V9 architecture that includes user instructions, supervisor instructions and hardware functionality. But the companies need to give programmers the tools to dig deeper into the hardware, as well as fine-tune systems that are encompassing more and more processors, he said.

In the CPU architecture itself, programmers need to have access to functions such as the memory management units and interrupts. Today, those can be defined by individual developers, but there is no way to do so across Sparc architectures from both companies. Since 1987, Fujitsu and Sun have been developing high-end Sparc processors for Solaris, but each has its own way of implementing the instruction set in hardware.

The reference platform will also allow users to address functions outside of the individual CPU. Those include hardware diagnosis, such as error correction; support for multiprocessing; interprocessor communication interrupts; and performance measurement mechanisms. Many of those enhancements will be reflected in a new operating system reference model.

Fujitsu, for one, is pushing hard to improve the scalability of its Sparc64 GP-based servers. Today it is shipping 8-way machines, and it plans to introduce a 64-processor system by early next year.
