This page provides the pure technical data about the Sphere SP 2.0 realtime microkernel.
The data presented refers to our reference hardware, an ACC Maple DX4-100 Processor with 2 MB of RAM, and to the 512-NFP-NIO-386 kernel configuration.

The data below may vary slightly on different systems. Especially the minimal application size, i. e. the minimum RAM usage for an application increases by about 7 KB per additional MB of RAM installed.

For information referring to your specific hardware please don't hesitate to contact us.
