Task management methods. A plurality of GBL (global bandwidth limiter) classes is provided. One of the GBL classes is selected based on the priority of a first task, in which the first task is from a MCU (micro-controller unit) bus. A system GBL class is selected based on the highest GBL class which has been selected among the GBL classes. A bandwidth limiter of a DMA (direct memory access) unit is assigned according to the system GBL class and the priority of a second task if the DMA unit is activated by the second task. The second task is from a DMA bus, and the cycle between the DMA and MCU buses is determined according to the bandwidth limiter.
