【英文介紹】
Features:
2eSST VMEbus protocol, the transmission rate across VMEbus is 320MB/s
Migration path from the existing MOTOROLA VMEbus platform
The high-performance MPC7457 PowerPC processor runs at 1.267 GHz
128-bit AltiVec coprocessor for parallel processing
Up to 1GB of on-board DDR ECC memory
Two 33/66/100 MHz PMC-X sites allow the addition of industry-standard, application-specific modules
Dual Gigabit Ethernet interface
128MB flash memory in two 64MB storage areas
The Emerson/MOTOROLA MVME6100 VME single-board computer is the first interface chip to deliver 2eSST VMEbus performance using the Tundra Tsi148 VMEbus design VMEbus. The 2eSST (Bilateral Synchronous Transmission along the Source) protocol allows the VMEbus to operate at an actual bandwidth of 320MB/s in most cases. The 2eSST protocol has been around for some time (a draft trial standard was published in 1999 and published as an ANSI standard in 2003), but so far, 2eSST boards have not been able to work in standard VMEbus backplanes. Because existing VMEbus transceivers cannot support the required VMEbus 2eSST signaling speeds. Texas Instruments (TI) has developed a new VMEbus transceiver that supports the VMEbus signal switching speed required by the 2eSST protocol. Combining the new Texas Instruments (TI) VMEbus transceiver and Tsi148 VMEbus legacy protocol support allows users to integrate the MVME6100 series into their existing infrastructure, providing backward compatibility.
