DYNAMIC MEMORY ACCESS MANAGEMENT

摘要

A system, a method and a computer program product for managing memory access of an avionics control system having at least one control computer having at least one memory control device. The method includes assigning a memory access of at least one unique memory region of at least one memory unit to each of at least one application task or task set. A memory access of at least one application data update task is assigned to at least one subregion of one or more of the at least one unique memory region. At least one data parameter is written to the at least one subregion and the assigned memory access of the at least one application data update task de-activated.

1. A method for managing memory access of an avionics control system having at least one control computer, the system comprising
at least one memory unit having a partitioning operating system and at least one application task or task set stored thereon, at least one processor arranged to orchestrate the partitioning operating system and the at least one application task or task set, at least one memory control device arranged to control memory access of the at least one processing device to the at least one memory unit, the method comprising: assigning each of said at least one application task or task set memory access to at least one unique memory region of said at least one memory unit, assigning at least one application data update task memory access to at least one subregion of one or more of the at least one unique memory region, orchestrating said at least one application data update task in order to write at least one data parameter to the one or more of the at least one subregion, and re-configuring the at least one memory control device in order to de-activate memory access of said at least one application data update task so as to protect said at least one subregion and thereby prevent any data parameter of the one or more of the at least one subregion to be overwritten.
