Abstract
Methods and systems for implementing a secure migratable architecture are disclosed. One method includes, upon initiating execution of a process, allocating a portion of a memory for use by the process during execution, the process including a firmware environment representing a virtual computing system having a second computing architecture different from a first computing architecture of a computing system on which the process is executed. The method also includes executing the process hosted by the operating system, wherein the firmware environment manages the portion of the memory using one or more area descriptors to describe the portion of the memory, each of the one or more area descriptors defining to the firmware environment a base address at which a memory area is located, the base address translated to an address in the memory managed by the operating system, the memory area being within the portion of memory allocated for use by the process.
