Abstract

Methods and systems for implementing a secure migratable architecture having improved performance features over existing virtualization systems are disclosed. One method includes allocating a portion of a memory for use by a process, 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 includes associating area descriptors with each of a plurality of memory areas within the portion of the memory used by the process, and receiving a request within the firmware environment to store data within a first memory area of the plurality of memory areas, the first memory area defined by a first area descriptor of the area descriptors, the request being associated with a plurality of memory addresses within the first memory area. The method includes, in response to the request, performing a check on a tag associated with the first memory area and stored in the first area descriptor. The method further includes, upon completion of the check, storing the data within the first memory area without performing a separate tag check for each of the plurality of memory addresses within the first memory area.
