Processor: AMD x86 Geode LX

NEPTUNE is DAVE Embedded Systems' answer to the x86 CPU modules demand. It's a general purpose microprocessor board powered by the AMD Geode LX CPU. But NEPTUNE is a step beyond the typical x86 architecture, offering something more attractive for the embedded world: Open Firmware, more powerful and flexible than a traditional BIOS, is DAVE Embedded Systems' choice as boot firmware for NEPTUNE.

NEPTUNE, due to its low power consumption (LX800 CPU is 0.9W) is suitable for single board computing or mobile computing applications, based on Linux but also on Windows operating systems. Leveraging on the x86 compatibility, NEPTUNE allows quick deployment of solutions based on software developed for the well-known x86 architecture.

The powerful FPGA improves NEPTUNE flexibility and allows customers to add specific interfaces to the design. The complete list of the available IP cores is reported here.
