Functional Characteristics
Microprocessor: The VMIVME-7648 brings the Intel Pentium III
processor to VMEbus, offering a processor speed of up to 1.26 GHz. 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.
DRAM Memory: The VMIVME-7648 accepts one 144-pin SDRAM
SODIMM for a maximum memory capacity of 512 Mbyte. The onboard
DRAM is dual ported to the VMEbus.
BIOS: System and video BIOS are provided in reprogrammable flash
memory (Rev. 1.02 is utilized from our VMIVME-7750 SBC).
Super VGA Controller: High-resolution graphics and multimedia quality video are supported on the VMIVME-7648 using the 815E AGP
graphics adapter. The adapter is complemented by 4 Mbyte external
synchronous DRAM cache with a high-bandwidth 64-bit data interface.
Screen resolutions up to 1,600 x 1,200 x 256 colors (single view mode)
are supported by the graphics adapter.
