GE VMIVME-7648 Single Board Computer

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 multimediaquality 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.

VMEbus Access manipulates the hardware behind the scenes. With  VMEbus Access, you can develop applications in or use existing  applications developed in most programming environments. For  example, VMEbus Access enables your VMEbus to recognize  applications developed in these popular programming environments:  

• IOWorks Manager™ 

• LabVIEW  

• Citect  

• Wonderware InTouch  

• Visual IOWorks® 

• Visual Basic® 

• Visual C++®

Watchdog Timer: 

The VMIVME-7648 provides a softwareprogrammable watchdog timer. The watchdog timer is enabled under  software control. Once the watchdog timer is enabled, onboard  software must access the timer within the specified timer period or a  timeout will occur. A user jumper allows the timeout to cause a reset.  Independent of the jumper, software can enable the watchdog timeout  to cause a nonmaskable interrupt (NMI) or a VMEbus SYSFAIL.

Nonvolatile SRAM: 

The VMIVME-7648 provides 32 Kbyte of  nonvolatile SRAM. The contents of the SRAM are preserved when +5 V  power is interrupted or removed from the unit.

PMC Expansion Site: 

The VMIVME-7648 supports IEEE P1386  common mezzanine card specification with a 5 V PCI mezzanine card  (PMC) expansion site. The PMC site provides for standard I/O out the  VMEbus front panel. An optional I/O connection to the VMEbus P2  connection can be provided.
