Abstract: Methods, systems, and computer readable media for automatic connection of software simulation models, for example and without limitation, for engineering simulation use in aircraft development are disclosed. According to one aspect, a method for establishing a communication link between software simulation models includes initiating communication between the software simulation models and a publish subscribe mechanism, classifying a quality of service indicator for each of the software simulation models, comparing the quality of service indicator associated with two software simulation models, and connecting the software simulation models based on the comparison of the quality of service indicators.

Abstract: This invention relates to a method for simulation of a computer system (10), for example for an aeronautical simulation application, comprising a hardware infrastructure (HW) and a software portion (SW). The method comprises: the modeling (E100) of the said hardware infrastructure (HW) in a plurality of schedulers (11-14) capable of simulating the successive execution of tasks (15, 40, 40?), the modeling (E110) of the said software portion (SW) in a plurality of initial tasks (15) comprising accesses to resources of the said hardware infrastructure (HW), the simulation (E130) of the initial tasks (15) comprising the software propagation of simulated accesses through schedulers (11-14) of the said modeled infrastructure (HW), the said propagation being carried out in the form of transactions (50) between pairs of schedulers (11-14), a transaction (50) comprising a task (40, 40?) on each scheduler and an indication of precedence (40?) linking the two tasks (40, 40?).

Abstract: A method for executing instructions on an application-specific microprocessor having a machine language is described. Microcontroller-like instructions are provided in a virtual language for execution on the processor. High-level DSP-like functions are compiled into DSP-like instructions in the machine language for execution on the processor. The microcontroller-like instructions are combined with the DSP-like instructions to produce a program, the program having a virtual language portion and a machine language portion respectively. When the program is executed, the virtual language portion of the program is translated into machine language instructions, and the machine language portion of the program is directly executed, such that the application-specific microprocessor executes both the DSP-like instructions and the microcontroller-like instructions.
