The GE Fanuc / VMIC VMIVME-7851 Single Board Computer brings the Intel Pentium 4 Processor – M to VME, offering processor speeds up to 2.2 GHz. The Intel Pentium 4 Processor – M is the first Intel mobile processor with the Intel NetBurst micro-architecture. The Intel Pentium 4 Processor – M utilizes a 478-pin, Micro Flip- Chip Pin Grid Array (Micro-FCPGA) package, and plugs into a surface-mount, Zero Insertion Force (ZIF) socket. The Intel Pentium 4 Processor – M maintains full compatibility with IA32 software.

The Intel NetBurst micro-architecture features include hyper- pipelined technology, a rapid execution engine, a 400 MHz ystem bus, and an execution trace cache. The hyper-pipelined technology doubles the pipeline depth in the Intel Pentium 4 Processor – M allowing the processor to reach much higher core frequencies. The rapid execution engine allows the two integer ALUs in the processor to run at twice the core frequency, which allows many integer instructions to execute in 1/2 clock tick. The 400 MHz system bus is a quad-pumped bus running off a 100 MHz system clock, making 3.2 Gbyte/s data transfer rates possible. The execution trace cache is a first level cache that stores approximately 12 Kbyte decoded micro-operations, which removes the instruction decoding logic from the main execution path, thereby increasing performance.

Additional features within the Intel NetBurst micro-architecture include advanced dynamic execution, advanced transfer cache, enhanced floating point and multimedia unit, and Streaming SIMD Extensions 2 (SSE2). The advanced dynamic execution improves speculative execution and branch prediction internal to the processor. The advanced transfer cache is a 512 Kbyte on-die level 2 (L2) cache. A new floating point and multimedia unit provides superior performance for multimedia and mathematically intensive applications.

Finally, SSE2 adds 144 new instructions for double-precision floating point, SIMD integer and memory management. Power management capabilities such as AutoHALT, Stop-Grant, Sleep, Deep Sleep and Deeper Sleep have been incorporated. The processor includes an address bus powerdown capability which removes power from the address and data pins when the system bus is not in use. This feature is always enabled on the processor.
