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 <a href="/wiki/Multidrop_bus" title="Multidrop bus">multi-drop bus</a> 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.

TAG bits are used to carry the flow control information. </p><p>SLIMbus Device Ports are associated with Data Channels using appropriate channel connection and dis-connection Messages. 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. A summary of the Transport Protocols is shown in Table 1. </p> <div style="float:left; position:relative; left:50%"><div style="float:left; position:relative; left:-50%"> <table class="wikitable"> <tbody><tr> <th>TP </th> <th>Protocol Name </th> <th>Type </th> <th># of TAG field Slots </th></tr> <tr> <td>0 </td> <td>Isochronous </td> <td>Multicast </td> <td style="text-align:center">0 </td></tr> <tr> <td>1 </td> <td>Pushed </td> <td>Multicast </td> <td style="text-align:center">1 </td></tr> <tr> <td>2 </td> <td>Pulled </td> <td>Unicast </td> <td style="text-align:center">1 </td></tr> <tr> <td>3 </td> <td>Locked </td> <td>Multicast </td> <td style="text-align:center">0 </td></tr> <tr> <td>4 </td> <td>Asynchronous – Simplex </td> <td>Unicast </td> <td style="text-align:center">1 </td></tr> <tr> <td>5 </td> <td>Asynchronous – Half-duplex </td> <td>Unicast </td> <td style="text-align:center">1 </td></tr> <tr> <td>6 </td> <td>Extended Asynchronous – Simplex </td> <td>Unicast </td> <td style="text-align:center">2 </td></tr> <tr> <td>7 </td> <td>Extended Asynchronous – Half duplex </td> <td>Unicast </td> <td style="text-align:center">2 </td></tr> <tr> <td>8 to 13 </td> <td>Reserved </td> <td style="text-align:center">- </td> <td style="text-align:center">- </td></tr> <tr> <td>14 </td> <td>User Defined 1 </td> <td style="text-align:center">- </td> <td style="text-align:center">1 </td></tr> <tr> <td>15 </td> <td>User Defined 2 </td> <td style="text-align:center">- </td> <td style="text-align:center">2 </td></tr></tbody></table> <div class="center" style="width:auto; margin-left:auto; margin-right:auto;">Table 1: SLIMbus Supported Transport Protocols</div> </div></div> <div style="clear:both;" class=""></div> <p>User 1 & 2 protocols are used to extend SLIMbus's data transmission mechanisms and it is assumed that a Device connected to a User Protocol Data Channel knows the definition of the TAG and AUX bits and how they are used. </p> <div class="mw-heading mw-heading2"><h2 id="SLIMbus_System">SLIMbus System</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SLIMbus&action=edit&section=20" title="Edit section: SLIMbus System"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A SLIMbus system for illustrative purposes only is shown in Figure 7 below.
