Arteris has raised $7.5 million in a third round of financing to fund its networking chip technology.

DoCoMo capital came aboard as a new investor, joining existing investors Crescendo Ventures, TVM Capital, Ventech and Synopsis Inc. in the round, according to VentureWire.

Current customers include STMicroelectronics NV and Texas Instruments Inc. The San Jose, Calif., and Paris, France-based company designs a chip interconnect technology that it licenses to chip design and chip making companies. It allows them to connect sections of a chip without the use of traditional buses, which take up a lot of space and are therefore costly to put on a chip.

The company’s technology is useful for companies designing “systems on a chip,” or those with multiple functions that have to be interconnected. Rivals include Sonics and Silistix.

To date, Arteris has raised $27.6 million in venture capital since 2003.
