Cells, Slots, Frames, Subframes, and Superframes. Return the logical address of a slimbus device. The Message Channel consists of all remaining Slots.

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. Completion to indicate end of message-transfer. The New Release, v2. Bandwidth allocation is done dynamically by the manager based on active channels epecification the bus, message-bandwidth requests made by SLIMbus devices.

Channel association of this port.

Xilinx going after Mellanox. The control channel is used for various control functions such as bus management, configuration and status updates. This page was last edited on 21 Julyat The Manager Device is responsible for configuring SLIMbus, and performs bus administration administration of Components and Devices, bus configuration, and dynamic channel allocation and is typically located in slibus baseband or application processor rather than in a peripheral component.


This port is not managed by the slimbus driver. Adding more channels or functions is difficult without increasing number of bus structures and hence pin count. Frames within a Superframe are labeled Frame 0 through Frame 7. Channels can be established between a pair of Devices inter-Device communicationor between one Device and many Specificatiob broadcast communicationor in the case of the Message Channel, from all devices to all other devices shared.

Manager, Framer, Interface, and Generic. All of the Components are different from each other. Used for messages expecting response.

January Learn how and when to remove this template message. 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.

Device notifications to the driver: Configure a port and make it ready for data transfer. Founded sslimbusthe organization has more than member companies worldwide, more than 15 active working groups, and has delivered more than 45 specifications within the mobile ecosystem in the last decade.

Payload of the message.

Slots used by message-bandwidth. Data channel uses dedicated ports on the device. Number of active coeffient 3 channels.

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. Port configuration for this port.

slimbus: Linux driver framework for SLIMbus.

This “guide byte” is normally 0, but if a control message straddles a Superframe boundary, it indicates the number of bytes until the end of that message. This communicates the Subframe length and the number of control Slots. Partner with us Visit our new Partnership Portal for more information. If the device is still there or if the address can be reused.


This structure has packet header, payload and buffer to be filled if any. Port request for this port. Root Frequency at which the framer can run. Controller to which this device is to be added to.

Controller with which device is enumerated. These messages can be unicast e. This API executes clock pause reconfiguration sequence if wakeup is false.

Mutex to protect the pending data-channel lists. Message to be sent by the controller. It has supporting bus arbitration mechanisms and message structures which permit re-configuring the bus operational characteristics to system application needs at runtime. Any mixture of audio related blocks could be attached.

Flow type of this port. 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.
