VMIVME7740-841

The VMIVME-7740 brings the Intel Pentium III processor to VMEbus, offering processor
speeds up to 850 MHz. The Pentium III processor has 32-bit addressing and a 64-bit data bus. Its superscalar architecture
allows three instructions to be executed per clock cycle. A dynamic branch prediction unit, separate instruction and data
caches, and MMX™ technology also increase the processor’s performance. The Pentium III processor also provides
256 Kbyte of Advanced Transfer Cache (on-die, full speed level 2 cache) using dual independent bus architecture for
high bandwidth and performance. This L2 cache operates at the same clock frequency as the processor, thus improving performance.

The VMIVME-7740 accepts one 144-pin SDRAM SODIMM for a maximum memory
capacity of 512 Mbyte. The on-board DRAM is dual ported to the VMEbus.
