The Serial Low-power Inter-chip Media Bus (SLIMbus℠) is a standard interface between baseband or application processors and peripheral components in mobile terminals. It was developed within the MIPI® Alliance, founded by ARM, Nokia, STMicroelectronics and Texas Instruments. The interface supports many digital audio components simultaneously, and carries multiple digital audio data streams at differing sample rates and bit widths. SLIMbus is implemented as a synchronous 2-wire, configurable Time Division Multiplexed (TDM) frame structure. It has supporting bus arbitration mechanisms and message structures which permit re-configuring the bus operational characteristics to system application needs at runtime. Physically, the data line (DATA) and the clock line (CLK) interconnect multiple SLIMbus components in a multi-drop bus topology. SLIMbus devices may dynamically “drop off” the bus and “reconnect” to the bus as required by using appropriate protocols outlined in the SLIMbus specification. When used in a mobile terminal or portable product, SLIMbus may replace legacy digital audio interfaces such as PCM, I2S,〔(【引用サイトリンク】url=http://www.classic.nxp.com/acrobat_download2/various/I2SBUS.pdf )〕 and SSI (Synchronous Serial Interface for digital audio), as well as some instances of many digital control buses such as I2C, SPI, microWire,〔(【引用サイトリンク】url=http://www.ti.com/lit/an/snoa743/snoa743.pdf )〕 UART, or GPIO pins on the digital audio components. == History == *The MIPI Alliance was formed in fall of 2003. * Interface architecture including a low speed media link bus (LowML) presented at the F2F meeting of MIPI Alliance in Sophia Antipolis, France in March, 2004. * LML Investigation Group (LML-IG) created in July 2004 by the MIPI Alliance. First meeting was a teleconference on 3-Aug-04. * LML Working Group (LML-WG) created in Q4 2004. LML WG Charter submitted to the MIPI Board in December, 2004. *First meeting as a full Working Group on 12-April-05. * LML-WG released first draft of SLIMbus with text in all chapters (v0.55) on 18-October-2005. * SLIMbus specification v1.00 was released to adopters on 16 May 2007. * From June 2007 to June 2008, SLIMbus specification improvement (ambiguities, typos & bugs fixed) based on implementer feed-back. * SLIMbus specification V1.01 was released to adopters on 3 Dec 2008 and is recommended for implementation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SLIMbus」の詳細全文を読む スポンサード リンク
