Product number :VMIVME-7750-746
Model :VMIVME-7750-746
VMIC VMIVME-7750-746 VMEbus single-board computer based on Intel Pentium II processor. 1.26GHz Pentium II supports 512K cache ISDRAM memory 128 MB ICOMpacflash - 128 MB Simple type: The CPU board VMIVME-7750 brings Intel Pentium II processors to VMEbus, offering processor speeds of up to 1.26 GHz. The Pentium II processor has 32-bit addressing and a 64-bit data bus. Its superscalar architecture allows three instructions to be executed per clock cycle. Dynamic branch prediction units, independent instruction and data caches, and MMX technology also improve processor performance. The VMIVME-7750 supports high-resolution graphics and multimedia quality video through the built-in 815E chipset AGP graphics adapter.
trait
■BIOS: The system and video BIOS are provided in reprogrammable flash memory. DRAM memory: The VMIVME-7750 accepts a 144-pin SDRAMSODIMM with a maximum memory capacity of 512 MB. The onboard DRAM is connected to the VMEbus via dual ports.
■ Flash memory: The VMIVME-7750 offers up to 1 GB of IDecompac Flash memory, which can be accessed via a secondary IDE port.
Timer: The VMIVME-7750 provides users with two 16-bit timers and two 32-bit timers (in addition to system timers). These timers are mapped in the I/0 space and are fully programmed by software.
■ Watchdog timer: VMIVME-7750 provides software programmable watchdog timer.
