Memory space allocation method and device, equipment and storage medium

The invention discloses a memory space allocation method and device, equipment and a storage medium. The method is applied to a data producer, and comprises the following steps: carrying out request monitoring on at least one data consumer, and when a memory allocation request is monitored, determining a to-be-processed image data volume according to the memory allocation request; determining a to-be-allocated memory space amount according to the to-be-processed image data amount; determining target node information based on idle linked list node information stored in a management memory area of a preset shared memory according to the memory space amount to be allocated; the target node information is fed back to the data consumer, so that the data consumer processes the to-be-processed image data based on the target node information; and according to the target node information, updating the idle linked list in the data memory area of the preset shared memory and the node state of the used linked list.
