微型芯片模块性能对照表 |
| |
CORE modules are tiny mezzanine single board computers.
They are designed for piggy-back attachment to a custom application
through high-density connectors, thereby providing a PC-on-chip equivalent
solution. |

Notes
- Height is specified without
heatsink.
For power dissipation above 5 watt, an additional heatsink
should be assembled.
- Power consumption depends on the
selected options and clock speed.
- General Purpose I/O are shared
with other functions.
- Performance measured with SiSoft
Sandra test bench under Windows NT.
- LCD interface of 786CORE requires
additional external logic.
- CAMI connectors - standardized
"CompuLab's Aggregated Module Interface" connectors,
enabling CORE module interchangeability.
