  • Method and a device for data transmission between an internal memory of a system-on-chip and an external memory
    Patent number: 11822958
    Abstract: A data transmission method and device for data transmission between an internal memory of a system-on-chip and an external memory coupled to the system-on-chip. The method is executed by a processor of the system-on-chip, including steps of: adding execution information of at least one data transmission task to be executed to a task queue; sending execution information of one data transmission task in the task queue to a direct access device for the direct access device to execute the data transmission task; and receiving an interrupt request sent by the direct access device, where the interrupt request is used to indicate completion of the execution of the data transmission task, so that the processor sends execution information of a next data transmission task to be executed in the task queue to the direct access device.
