The present application relates to a data processing method for a numerical control system, a computer device and a storage medium. The method comprises: receiving a data request, the data request carrying a target data identifier; parsing the data request to obtain an interactive type corresponding to the target data identifier; when the interactive type corresponding to the target data identifier is a type corresponding to real-time data, searching for data corresponding to the target data identifier in a shared memory of the numerical control system; transferring the data corresponding to the target data identifier from the shared memory to a data cache of the numerical control system and outputting the data.

Disclosed in the present application are a method and device for managing a shared memory in a robot operating system. A detailed embodiment of the method comprises: acquiring a shared memory registering service request transmitted from a message receiving node, the shared memory registering service request comprising a topic name and a size of a required memory segment; requesting a memory segment in a shared memory area based on the size of the required memory segment, associating the topic name with the requested memory segment, and saving the topic name in a configuration file; dividing the requested memory segment into a plurality of memory blocks based on a size of a message transmitted from a message transmitting node; and deallocating the requested memory segment where any one of following conditions is satisfied: the topic name in a main node is inconsistent with that in the configuration file, the message transmitting node and message receiving node stop working, and the message receiving node stops subscribing to a topic corresponding to the topic name. By means of the embodiment, the shared memory of the robot operating system is allocated and managed more reasonably and flexibly.

An integrated controller for motion control and motor control comprises a first processor, a second processor, a cache and a shared memory. The first processor is configured to run an operating system and at least perform motion control. The second processor is configured to at least perform motor control and normally not run the operating system. The cache is coupled to the first processor and the second processor. The shared memory maps onto the cache. The first processor and the second processor are configured to share the shared memory and accordingly perform data transmission via the cache during the periods of motion control and motor control. The first processor, the second processor and the cache are integrated in a same chip.
