Method for realizing hard real time virtual timer response of embedded virtual machine

Abstract

The invention discloses a method for realizing hard real time virtual timer response of an embedded virtual machine. The method is characterized by comprising the following steps that through building a timer interrupt distribution table in Hypervisor, a limited hardware timer is interrupted, and the direct distribution is carried out through the interrupt distribution table of the Hypervisor, so the delay caused by the original modes of virtual machine event channels, virtual clocks and the like can be reduced, and in addition, the sharing of the limited hardware timer interrupt in an embedded processor platform at a plurality of partitions can be realized. The method has the advantages that the delay caused by the original modes of the virtual machine event channels, virtual clocks and the like is reduced, and in addition, the sharing of the limited hardware timer interrupt in the embedded processor platform at a plurality of partitions can be realized, so the precision and the response speed of the virtual timer of the virtual machine partitions can be respectively improved and accelerated, and finally, the great problem encountered by the application of the embedded virtualization technology to the field of aerospace is solved.

AI Technical Summary

Benefits of technology

This patented method allows for more precise timing between different parts within an electronic system than previously possible due to its use of specialized software called timers that are controlled remotely from other components on-board it's main purpose. By sending specific instructions over this communication path instead of relying solely upon predefined rules or commands provided by external sources like timepieces, these methods improve overall performance while minimizing delays associated with events occurring during flight operations.

Problems solved by technology

Technological Problem addressed in this patents relates to the limitations associated with current virtual reality software architectures due to delays caused by transmission of interrupt signals from various components within these environments like flight controls and space vehicles. These issues include increased latency when updating critical timing counters on different parts of the architecture without taking into account any delay differences among them. Additionally, there is no guarantee for accurate synchronizing times across all three dimensions of the structure being controlled remotely.
