Embodiment Construction

[0048] The information processing device, communication processing method, and computer program of the present invention will be described below with reference to the drawings.

[0049] Refer below figure 1 The hardware configuration of the information processing device of the present invention will be described. The processor module 101 includes a plurality of processing units, and processes data according to various programs stored in a ROM (Read Only Memory) 104 and an HDD (Hard Disk Drive) 123, including an operating system and running application. The following will refer to figure 2 Now, the processor module 101 will be described.

[0050] In response to commands input via the processor module 101, the graphics engine 102 generates data to be displayed on a screen such as a display forming the output unit 122, and performs 3D graphics rendering processing. A main memory (DRAM) 103 stores programs executed by the processor module 101 and parameters that change during...

Abstract

There are provided a device and a method for realizing smooth message transfer between operating systems (OS). A message transfer control between OS is performed by executing the mapping state switching of the message area in the physical address space in a multi OS environment from a message area of the logical partition address space of the message transmission side OS to the message area of the logical partition address space of the message reception side OS. Moreover, a socket correlated to a file descriptor is generated and a virtual file accessible via the socket is set, thereby transmitting and receiving a message by applying a mapping of the message area of the virtual file and the physical address space.

Description

technical field [0001] The present invention relates to an information processing device, a communication processing method and a computer program, and in particular to an information processing device, a communication processing method and a computer program for controlling message transmission between operating systems in a multi-operating system. Use multiple operating systems to perform processing. Background technique [0002] In a multi-operating system having a plurality of operating systems (OS) in a single system, each operating system can execute an individual process, and sequentially switch system-common hardware such as a CPU and a memory in chronological order. [0003] Scheduling of processes (tasks) of a plurality of operating systems is performed, for example, by a partition management software program. If OS(α) and OS(β) coexist in a single system and the process of OS(α) is Partition A and the process of OS(β) is Partition B, the partition management soft...
