MCGI SIngle Board Computer
The MCGI PICMG 1.3 System Host Board

The MCG series of PICMG® 1.3 System Host Boards offers a wide variety of board configurations designed to excel in the most demanding graphics-class computing applications. Dual-Core processor options provide two and Quad-Core processors provide four execution cores per processor. For dual-processor board configurations, each processor has its own independent system bus to reduce data bottlenecks while maximizing processing throughput. The four-channel memory interface features DDR2-667 FB-DIMMS with a maximum of 16GB. An extended-memory SHB configuration is available that supports up to 32GB of system memory. The processing power and configuration flexibility built into the MCG-series give system designers and their customers the best technology fit for their graphics-class PICMG 1.3 computing applications.

Model number and model name definitions:

6680 MCGT = two processors, standard-memory configuration
6675 MCGI = one processor, standard-memory configuration
6690 MCGT-E = two processors, extended-memory configuration
