Intel will ship a Pentium M-based system-on-chip (SoC) for consumer devices like networked optical players, set-top boxes, and digital TVs. The 800MHz Media Processor CE3100 ("Canmore") aims to bring YouTube and other PC-based entertainment platforms to home entertainment systems, where today MIPS-based SoCs from Sigma, Broadcom, and others dominate.


Intel calls the CE 3100 "the first in a new family" of SoCs aimed at the consumer electronics segment. More specifically, it targets network-enabled optical drives and set-top boxes, where today MIPS is probably the dominant architecture, thanks to popular offerings from Sigma, Broadcom, and others. Intel appears to be hoping that x86's better support for the software needed to run YouTube and other PC-based entertainment platforms will help it compete, as the PC and CE markets continue to converge.

609 signal pins in a 37.5mm lead free FC-BGA7 (1434 balls) packageEric Kim, GM of Intel's digital home group, stated, "The Web is quickly moving to the TV. [The CE 3100 is our] first IA SoC with Internet compatibility for consumer electronics devices."

Canmore appears to be Intel's second x86-based SoC, and its first for consumer electronics devices. The company earlier shipped the EP80579 ("Tolapai"), also based on a Pentium M core, and targeting storage applications.

Intel based previous CE-series chips, such as the CE 2110, on the ARM architecture.

System-on-chip processors typically integrate a CPU core with memory and storage controllers, display controllers, on-chip peripheral interfaces, and specialized hardware subsystems such as security co-processors, all on the same physical die.

Availability

The CE 3100 will ship next month. Early customers reportedly include Samsung and Toshiba. Pricing was not stated.
