Building on the efforts of an Investigation Group formed in late 2004, the MIPI Board chartered the Low Speed Multipoint Link Working Group in mid-2005 to support audio, data and control applications requiring relatively low bandwidth. The efforts of many audio codec, application processor, baseband, and other companies produced the first Serial Low-power Interchip Media Bus (SLIMbus®) Specification in 2007. The group has continued its work updating SLIMbus in the interim, and recently completed work for the first version of SoundWireSM, a complementary Specification with a particular focus on lower-complexity peripherals.
These Specifications each allow system integrators lower overall system cost and more flexible system designs by consolidating several diverse functions, usually implemented on separate legacy interfaces, onto one dynamically reconfigurable multidrop bus offering peer-to-peer communication.The working group continues to investigate ways to optimize its Specifications for power and speed to lower the technical barriers to adoption, and promote SoundWire and SLIMbus within the industry.
