SPACE COMPUTING PRODUCTS - RELATIVE PERFORMANCE

There are many attributes and trade-offs when comparing performance between computing platforms. These graphs give an idea of how the different models compare to each other. These represent a comparison of Q-Card processor boards; daughterboards may add additional resources.

Q8 - 01 Q8 - 02 Q8 - 03 Q8 - 04 Q8 - 05 Q8 - 06

 * The Q9 A72 supports out of order execution, larger cache, and faster clock speed etc.

FULLY FLEXIBLE

Your OBC should enable your spacecraft platform design, not limit it. The Xiphos toolchain gives you full control over the FPGA fabric and Linux Operating System environment.

Its reconfigurable 3v3 GPIO and LVDS pins allow for custom interfaces, while flexible RS-422/485/232 serial settings make it easy to adapt to your hardware suite.
