Arteris Inc. has unveiled its FlexLLI digital controller IP that implements the MIPI Alliance Low Latency Interface (LLI) 1.0 interchip communication specification. According to the company, the chip to chip interface IP is silicon proven, having been implemented in the industry's first SoCs that have LLI, including the OMAP5430 from TI.

Arteris FlexLLI offers a point-to-point interconnect between two chips such as a mobile phone application processor and modem baseband processor. Using this high bandwidth, LLI enables the modem baseband processor to access the application processor's dedicated DRAM for modem operation, eliminating a separate, dedicated modem baseband DRAM chip. Industry estimates translate this savings to about $1 to $2 reduction in the total BoM cost for a smartphone. PCB space and thickness is also saved, giving mobile device manufacturers a win-win solution to create smaller and thinner devices, stated the company.

The digital MIPI LLI IP reduces design cost and compatibility risk while accelerating time to market, said Arteris. This configurable IP connects with SoC interconnects using AMBA AXI, OCP and proprietary protocols, as well as Arteris FlexNoC network on chip interconnect IP. FlexLLI also interfaces with commercial MIPI M-PHY IP such as the Synopsys M-PHY, as well as internally-developed M-PHYs.

Arteris FlexLLI MIPI LLI IP is available today.
