Intel Expands Semiconductor IP in Handset Bid

The processor giant seems serious about the handset market as shown by its BIOS collaboration with Phoenix and acquisition of Interdigital 3G patents.

Several recent announcements suggest that Intel wants to become a significant player in the rapidly expanding mobile handset market.

The first story seems innocuous enough. Phoenix Technologies, a long-time developer of PC Basic Input Output System (BIOS) firmware, recently announced an agreement with Intel to jointly develop the new reference Unified Extensible Firmware Interface (UEFI) for the Intel code base.

BIOS boot firmware is the first code to run when a PC is powered on. In a drive (no pun) to modernize the booting process, the UEFI community has created a specification to define the software interface between an operating system and platform firmware (Figure 1). This specification was designed to be both processor- and device driver-independent. UEFI capable systems are already been shipped by major desktop OEMs.

Most PC motherboard suppliers license a BIOS core from third-party vendors like American Megatrends (AMI), Insyde Software and Phoenix Technologies. The board suppliers then customize the BIOS core to address different hardware needs for their various product lines.

The processor- and driver-independent nature of the UEFI specification complements Phoenixs latest Secure Core Technology (SCT) tool that enables a universal build environment. This means that a single BIOS can be used across numerous operating systems and silicon platforms, thus improving code efficiency and reliability. SCT is targeted at servers, notebooks, desktop and embedded devices.

According to Steve Chan, Phoenixs CTO, the company has engagements with Intels desktop PC client group to collaborate on a reference BIOS. Additionally, the company is providing engineering support to Intels server group. When asked if the reference BIOS would be used on embedded Intel products including mobile, Chan could only say that the BIOS could be applied across all platforms.

The question concerning cross-platform BIOS development is important as it suggests further evidence that Intel is serious about the handset and tablet markets. Earlier this year, the company announced that the European carrier Orange would support its single-core Intel Atom processor Z2460 powered handset running the Googles Android operating system (Figure 2).

Additional evidence of Intels move into the handset space comes from its recent acquisition of the Interdigital wireless patent portfolio. Interdigitials patents cover 3G and newer wireless technology used by both computer and mobile phones.

In collaborating with or acquiring patent-rich companies, Intel is employing a strategy common to handset and tablet manufacturers. By amassing a large number of IP and patents, companies hope to strengthen their negotiating power among rivals. Currently, Apple, Motorola, Google, HTC and Samsung to name a few are involved in lawsuits that began as patent disputes.
