Slimbus specification “guide byte” is normally 0, but if a control message straddles a Superframe slimbus specification, it indicates the number of bytes until the end of that message. Join the Mailing List. Retrieved 17 January All SLIMbus Devices use DATA and CLK to synchronize with the bus configuration in use, to receive or transmit messages and data, and to implement bus arbitration, collision detection, and contention resolution between devices.

Computer buses Slimbus specification Industry Processor Interface standards. SLIMbus Components convey control and data information between each other using Control and Data Channels with Slimbus specification Protocols to achieve the required system operation. Please help specifivation it or discuss these issues on the talk page.

Cell, Slot, Subframe, Frame Structure. A Data Channel, and therefore slimbus specification structure of a Segment, is defined by parameters such as Data rate, type, field length, and required Transport Protocol.

The Framing Channel occupies Slots 0 and 96 slimbus specification each Frame. This page was last edited on 21 Julyat Over the course of a Superframe, 32 bits of Framing Information are slimbis. Please help improve this article by adding links that are relevant to the context within the existing text. Views Read Edit View history.

A Data Channel has exactly one data source at a time and may have one or more data sinks depending upon the Transport Protocol used in the channel. Members of the organization include specjfication manufacturers, device OEMs, slecification providers, semiconductor companies, application processor developers, IP tool providers, test and test equipment slimbus specification, as well as camera, tablet and laptop manufacturers.


Another feature is multichannel capability that can transmit multiple, phase-aligned audio streams between multiple devices and peripherals; the multichannel feature can slimbus specification support phase-coherency, improved direct memory access Slimbus specification efficiency, and higher bandwidth via a slimbus specification number of ports to simplify integration and improve use of limited board space in a device.

A Generic Device is generally considered to be the device to provide certain application functionality, for example, conversion from digital audio to analog DAC and vice versa ADC. A third feature is a segment distribution technique that uses new secondary data transport lines to maximize the use of available bandwidth for asynchronous data transmissions; this feature can improve performance for pushed or pulled data, software downloads, slimbus specification uploads or bulk data transport.

Messages are used for Control functions. The specification supports a wide range of digital audio slimbus specification control solutions to seamlessly transport audio and related data for larger-sized mobile device components, such as the application processor, audio codec, modem, audio digital signal processor, Bluetooth, and FM receiver.


Slimbus specification help to improve this article by introducing more precise citations. The specification also supports software configuration, which enables system flexibility. TAG bits are used to carry the flow control information. A Superframe is defined as eight contiguous Frames Slots. The number of possible Subframes per Frame is therefore 32, 24, 8, or 6 respectively. The remainder is available for more general control messages. Slimbus specification Cell slimbus specification defined as a region of the DATA signal that is bounded by two consecutive positive edges of the CLK line and holds a single bit of information.

As shown in Figure 4 below, the Subframe length is programmable to 6, 8, 24 or 32 contiguous Slots 24, 32, 96 or Cells. It has supporting bus arbitration mechanisms and message structures which permit re-configuring the bus operational characteristics to system application needs at runtime. Slimbus specification duration of a Superframe is fixed in terms of Slots and, therefore, Cellsbut not in terms of time. Flow Control in the Channel, if needed, depends on the Devices and the type of Data involved.


Bandwidth allocation for various data organizations, from slimbhs to bits or more, can be done by grouping 4-bit Slots. The format of Control Space is determined by a 5-bit Subframe mode identifier transmitted in the Framing Information slimbus specification.

For data flow between Ports attached to Channels, SLIMbus supports a small group of frequently used Transport Protocols including a User Defined Transport Protocol which define data flow type, flow control mechanism, and a side-channel if any for any additional application-specific information.

Cells, Slots, Frames, Subframes, and Superframes. Founded slimbus specificationthe organization slimbus specification more than member companies worldwide, more than 15 active working slimbus specification, and has delivered more than 45 specifications within the mobile ecosystem in the last decade.

This article has multiple issues. Frames within a Superframe are labeled Frame 0 through Frame 7.

The number of control Slots is slimbus specification to the choices of dpecification, 2, 3, 4, 6, 8, 12, 16, or All of the Components are different from each other. The DATA line can be driven high, driven low, or held at the high or low level by an internal bus-holder circuit, depending upon the particular operational mode of a SLIMbus Device. A summary of the Transport Protocols is shown in Table 1.

Adding the limitations that the number of control Slots must be less than the Subframe length produces 26 valid combinations. Modes 1—3, 20 and 30 are not slimbus specification. Figure 8 below shows a conceptual view of a possible real world SLIMbus system.

This communicates the Subframe length and the number of control Slots. This article needs more links to other articles to help integrate it into the encyclopedia. It carries slimbus specification types of information including bus configuration announcements, Device control and Device status. Any slimbus specification of audio related blocks could be attached. The techniques facilitate interoperability, reduce time-to-market and lower design costs by simplifying the interconnection specificatoon products from different manufacturers.
