Information processing apparatus, information processing method, and non-transitory computer readable medium

摘要

An information processing apparatus includes first and second central processing units, a communication unit, and a memory. The first and second central processing units operate based on first and second operating systems, respectively. The communication unit controls communication between the first and second operating systems. The memory includes first and second memory areas used respectively by the first and second operating systems. The first operating system includes a memory access requesting unit. The memory access requesting unit sends, to the second operating system via the communication unit, a request to write information to be moved from the first memory area to a virtual memory and a request to read information to be moved from the virtual memory to the first memory area. The second operating system writes to and reads from the second memory area, the information indicated by the write and read requests, respectively.

主权项

1. An information processing apparatus comprising:
a first central processing unit configured to execute a first operating system having a virtual memory function of accessing secondary memory resources; a second central processing unit configured to execute a second operating system; a communication unit that controls communication between the first operating system and the second operating system; and a memory coupled to the first central processing unit and the second central processing unit, the memory comprising a first memory area permitted to be used by the first operating system and a second memory area permitted to be used by the second operating system and not permitted to be used by the first operating system, wherein the first operating system is configured to send, to the second operating system, a write request to write information to memory resources accessible to the second operating system, and to send a read request to read information from the memory resources accessible to the second operating system, and wherein the second operating system is configured to write, to the second memory area, the information indicated by the write request, and to read, from the second memory area, the information indicated by the read request and provide the read information to the first operating system.
