LG Electronics selects ARM Optimode DSP for HDTV

LG Electronics Inc. has licensed the Optimode digital signal processing technology from ARM Holdings plc, a licensor of processor designs, for use in video encoding and decoding product lines, ARM said Wednesday (Jan. 5).

The first LG product to use Optimode is set to be an H.264 based high-definition digital television (HDTV), which would use Optimode to process HDTV frame rates and frame sizes, while retaining reprogrammablity to accommodate multiple video decoding standards, ARM said. LG Electronics joins French consumer electronics giant Thomson SA in licensing the Optimode technology.

Optimode is a configurable VLIW-styled architecture intended for embedded signal processing applications with an associated tool chain. The tool environment enables the designer to configure and extend the type and number of data path resource units. The size and topology of local storage and the level of interconnect are also configurable. The Optimode configuration is programmed in either C or C++ and is provided with a C compiler and profiling analysis tools.

ARM said in a statement that LG selected Optimode instead a wide range of other programmable digital signal processing technologies. Such technologies would typically come from ARM's integrated device manufacturer partners, but as ARM has moved into other areas than its historical position in RISC processors, it runs the risk of competing with some customers.

ARM took a more competitive stance in 2004. The company updated its "vision statement" and said in May 2004, the time when ARM introduced the Optimode product. ARM said that from that time forward it aimed to have its intellectual property in every digital integrated circuit that is produced anywhere in the world. ARM chairman Sir Robin Saxby was quoted in November 2003 as saying that within partnerships it may be necessary to upset partners "a little bit", or risk achieving nothing.

"LG Electronics is further proof that Optimode technology is providing our partners with an improved approach and necessary alternative to digital signal processing solutions," said Tom Cronk, data engines general manager at ARM, in a statement.
