Abstract

A system for porting code from a native platform to a non-native platform is provided which utilizes a non-native, platform-specific layer of code and a platform-neutral layer of code. The platform-neutral layer substantially emulates the native platform of ported code and provides a platform-neutral interface to the ported code. Together, the platform-specific layer and the platform-neutral layer provide an execution environment in which the ported code operates as a kernel extension of the non-native platform. The platform-neutral layer of the execution environment is portable to other non-native platforms so that code can be ported to another non-native platform by replacing the platform-specific layer with a customized platform-specific layer, which is adapted to the other non-native platform.
