The VMIVME-7750 brings the Intel Pentium III processor to VMEbus, offering processor speeds 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 (1.26 GHz has 512 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.
