VME64 gets high-performance FDDI
Board becomes the first VME implementation of the National Semiconductor
FDDI chip set
Designed to take advantage of the potential of multimode optical fiber,
the PT-VME600 FDDI node adapter for VME64 provides a 100-Mbit/s
transmission path between nodes. The board uses National Semiconductor's
third-generation MACSI and Player+ FDDI interface chipset. The LSI version
of the Mips Computer LR3000 RISC microprocessor running at 25 MHz is also
incorporated on the board. Flexibility is provided for, with the board
available as a single- or dual-attach station, along with options for
fiber or copper network interfaces. The extended PT-VME61x family includes
configuration support allowing multiple modules to be interconnected. The
adapter includes two module-resident memory arrays–a 256-Kbyte frame
buffer to isolate the VMEbus and microprocessor from the network
interface, and 2 or 4 Mbytes of dedicated code store and execution DRAM
for the microprocessor. Data transfer rates of up to 60 Mbytes/s over the
VMEbus are possible in VME64 mode. Software support includes XLNT Design
Rev. 6.2 SMT along with device drivers for Unix SR5. ($3,996 ea/100–stock
