Document Type and Number:
Japanese Patent JP7250651
Kind Code:
B2
Abstract:
To provide a work machine that can perform arithmetic processing by a plurality of applications without impairing arithmetic processing of an important application.SOLUTION: A work machine includes: a GPU 93 having a GPU dedicated area 93a for executing a priority application set as arithmetic processing to preferentially perform arithmetic and a GPU shared area 93b for executing a non-priority application different from the priority application; and a GPU arithmetic management unit 92a that manages execution of the priority application in the GPU dedicated area 93a and execution of the non-priority application in the GPU shared area 93b. When the priority application and the non-priority application are requested, the GPU arithmetic management unit 92a distinguishes arithmetic which is prioritized and arithmetic for which delay is allowed, performs the arithmetic which is prioritized as the priority application using the GPU dedicated area 93a, and performs the arithmetic for which delay is allowed as the non-priority application using the GPU shared area 93b remaining for the GPU dedicated area 93a.SELECTED DRAWING: Figure 4
