The techniques facilitate interoperability, reduce time-to-market and specificagion design costs by simplifying the interconnection of products from different manufacturers.

A Subframe is partitioned into 1 or more slots of Control Space, followed by 0 or more slots of Data Space. A Generic Device is generally considered to be the device to provide certain application functionality, for example, conversion sprcification digital audio to analog DAC and vice versa ADC. Pointer to access routines. Message code for type mt.


Request to reserve bandwidth for messages. Retrieved from ” https: Input structure for start-offset, number of bytes to read. Members of the organization include handset manufacturers, device OEMs, software providers, semiconductor companies, application processor developers, IP tool providers, test and test equipment companies, as well as camera, tablet and laptop manufacturers. Root Frequency at which the framer can run. Cells, Slots, Frames, Subframes, and Superframes.

Coefficient of a channel used internally by framework. This article needs more links to other articles to help integrate it into the encyclopedia. Unsourced material may be challenged and removed.


Used during scheduling to new interval temporarily. From Wikipedia, the free encyclopedia. Slimbus controller managing the bus hosting this device. The Specifocation 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. Called to schedule a transfer on port pn. Controller with which device is enumerated. Segments repeat at known intervals and behave as virtual bus’s with their own bandwidth guarantee and latency.

Bandwidth allocation for various data organizations, from 4-bits to bits or more, can be done by grouping 4-bit Slots. There are 10 clock gears and each gear changes the SLIMbus frequency to be twice its previous gear.

To support that behavior, the framework allows drivers to probe first as well e. Slot 0 holds a fixed Frame Sync symbol 2while Slot 96 holds 4 bits of a Framing Information word. 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.

Alternatively, the multi-mic array could replace the single mic in the system. Buffer to be populated by controller when response is received. Message bandwidth reserved by this client in slots. Since all Subframe lengths divide 96, these Slots are always available for the purpose. The format of Control Space is determined by a 5-bit Subframe mode identifier transmitted in the Framing Information word. Superframes per root frequency. Port configuration for this port. Slimbus specification needs this sequence to turn-off clocks for the bus.


Messages are used for Control functions. Current subframe-code used by TDM. Elemental address of the device.

Number of active coeffient 1 channels. Adding more channels or functions is difficult without increasing number of bus structures and hence pin count. A Cell is 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.

Sample size in bits. This eliminates a lot of boilerplate. Cell, Slot, Subframe, Frame Structure.

October Learn how and when to remove this template message. SLIMbus mandates that a reconfiguration sequence known as clock-pause be broadcast to all active devices on the bus before the bus can enter low-power mode.

slimbus: Linux driver framework for SLIMbus.

Controller to which this device is to be added to. Message to be sent by the controller. The New Release, v2. Connect port s to channel. Channel structure used externally by users zpecification channel APIs. Refer to enum above. Interval of this channel per superframe.

Minimum clock gear supported by this controller default value: The specification also supports software configuration, which enables system flexibility. Every bus has 1 active manager.

Configure a port and make it ready for data transfer.
