Information processing device, information processing method, and robot apparatus

Abstract

A robot device (1) has a central processing process (CPU) having a plurality of objects and adapted for carrying out control processing on the basis inter-object communication carried out between the objects, the central processing process controlling accesses by the plurality of objects to a shared memory shared by the plurality of objects and thus carrying out inter-object communication. Specifically, the central processing process generates pointers P 11 , P 12 , P 13 , P 21 , P 22 in accordance with accesses by the objects to predetermined areas M 1 , M 2 on a shared memory M, then measures the pointers by the corresponding number-of-reference measuring objects RO 1 , RO 2 , and controls the accesses in accordance with the number of pointers measured, thereby carrying out inter-object communication. This enables easy realization of smooth inter-process communication.

Description

technical field

[0001] The present invention relates to an information processing device and an information processing method that execute various processes using a plurality of processes, and a robot device that determines its actions, etc., using a plurality of processes. Background technique

[0002] In the case of communicating among a plurality of distributed processes (inter-process communication) to execute a task in real time, the progress state of the task differs according to the weight, priority, processing cycle, etc. processed by each process. For example, if the processing result (data) of process A executed at high speed is sent from process A to process B executed at low speed, process B fills the queue received from process A, and the received queue overflows. The problem of queue overflow occurs at various points in real-time system operation. In order to prevent this problem, handshaking between processes must be done through a sp...
