摩托罗拉MVME6100 VME单板计算机是首 款采用Tundra Tsi148 VMEbus接口芯片设计的VMEbus单板计算机(SBC)，提供2eSST VMEbus性能。2eSST(两个边缘源同步传输)协议使VMEbus在大多数情况下以320MB/s的实际带宽运行。2eSST协议已经存在了一段时间(试用标准草案于1999年发布，并于2003年作为ANSI标准发布)，但直到现在，2eSST板将无法在标准VMEbus背板上工作，因为现有的VMEbus收发器无法支持所需的VMEbus 2eSST信令速度。德州仪器公司开发了新的VMEbus收发器，支持2eSST协议要求的VMEbus信号交换速度。新的德州仪器VMEbus收发器和Tsi148 VMEbus传统协议支持的组合允许用户将MVME6100系列集成到现有的基础设施中，提供向后兼容性。

The Motorola MVME6100 VME Single-Board Computer is the first VMEbus single-board computer (SBC) designed with the Tundra Tsi148 VMEbus interface chip offering 2eSST VMEbus performance. The 2eSST (two edge source synchronous transfer) protocol causes the VMEbus to run at a practical bandwidth of 320MB/s in most cases. The 2eSST protocol has existed for some time (the draft standard for trial use was published in 1999 and released as an ANSI standard in 2003), but until now, 2eSST boards would not work in a standard VMEbus backplane because the existing VMEbus transceivers could not support the required VMEbus 2eSST signaling speeds. Texas Instruments has developed new VMEbus transceivers that support the VMEbus signal switching speeds required by the 2eSST protocol. The combination of the new Texas Instruments VMEbus transceivers and the Tsi148 VMEbus legacy protocol support allows users to integrate the MVME6100 series into existing infrastructure providing backward compatibility.
